Chinese Aerospace at Oshkosh

The Chinese presence at Oshkosh, the world’s premiere general aviation event, consisted primarily of two aircraft: the Cessna 162 Skycatcher and the Yuneeq electric airplanes. The Skycatcher was approved by the FAA in the Light Sport category last year. However, only eight examples have been produced in the Shenyang factory. So far it is not a great example of the power of Chinese manufacturing applied to light aircraft, though some of the delay in production may be due to problems with the aircraft’s spin characteristics.

The Yuneec E430 got a lot more attention. It might be fairer to call it a one-seat motorglider rather than an airplane, but it has substantial range and points toward electric airplanes with a lot of practical value, e.g., for flight training. Since the Chinese are the world leaders in battery manufacturing they presumably should have a good chance in becoming the world leaders in electric aircraft (though with the Solar Impulse, the Europeans are also doing some very interesting stuff).

Wandering around Oshkosh

Getting around Oshkosh involves a lot of meandering through parking lots. As many as 100,000 people will drive in to enjoy the show on any given day. Thus tens of thousands of cars with Wisconsin, Minnesota, and Michigan plates surround the airfield. Having lived in Massachusetts for decades, I’m accustomed to cars whose owners have chosen to show the world how much smarter they are than average. The typical Prius in Cambridge, for example, will display bumper stickers showing that the owner voted for a slate of politicians who’ve promised to make the world a better place. These are augmented by direct statements of the owner’s plans for how other people should behave, e.g., a “Coexist” admonition with various religious symbols juxtaposed. How do they do it in the Midwest? The posteriors of the thousands of cars I walked by were shockingly naked. The handful of bumper stickers that I did see were references to obscure products for which the owner presumably had an enthusiasm. I did not see a single political bumper sticker nor any advocating a social cause.

Most of our evenings in Oshkosh were occupied with dinners for Experimental Aircraft Association supporters. At one we sat next to a quiet Air Force veteran named Blair Bozek. He had served as a crewmember on the SR-71 for 70 operational missions. Did he have any problems with the machine? we asked. “Just the usual hydraulic and electrical glitches,” was his response. We later Googled and found out that he’d had to eject out of a failed SR-71 and swim around in the South China Sea for a while. We decided to give him our “Master of Understatement” award.

A fundraising dinner for the EAA Young Eagles program yielded $2.1 million for a variety of items in a live auction. Generally the TV cameras would swing around to show the happy high bidder at the end of the auction for each item, e.g., a $375,000 customized Ford Mustang. Seemingly invariably it would be a pudgy grey-haired white guy sitting next to an attractive young blonde. I can’t quite figure out why Young Eagles needs so much money to operate, since the program is organized by local volunteers at various airports around the country. The actual rides for young people are given by local airplane owners who are not compensated. I have mixed feelings about the program. If someone said “I introduce young people to something fun, unnecessary, dangerous, and expensive”, my first thought would be “drug dealer”. There are a lot of programs to encourage young people to pursue careers in aviation. Is it kind to steer a young person toward a career in which there are 10 qualified people for every job? When the same young person could go into medicine and pick from 10 job openings for every qualified person?

Six of us found ourselves free one evening and of course ended up at Naughty Girls. My previous experience with gentlemen’s clubs had been in Canada. How does the American/Wisconsin strip club experience differ? Let’s just say that as a 6′ tall guy carrying some extra middle-aged weight you would have to abandon any idea that the strippers should be lighter than you. The high point of my evening was watching the youngest member of our gang (about 24 years old) put a dollar bill into a dancer’s panties while seemingly standing in a different zip code.

Oshkosh early report

We arrived at Oshkosh on Tuesday after stopping in Buffalo to pick up Thurman Thomas (a VIP guest of EAA). Arriving in a turbojet IFR meant that we didn’t have to follow any of the traditional Oshkosh “look for the water tower” and “rock your wings” procedures. After landing Runway 27 we turned right and parked and were whisked away to a little caravan of RVs. Then we were given a tour of the convention by an unassuming volunteer, Jeffrey Gentz, who lives in the area and has been volunteering at Oshkosh for 30 years. We had to ask if he had any flying experience himself. “Mostly on the MD11 at UPS,” he noted, “where I also do training, but I’ve also flown the 757/767.” Jeff delivered us finally to a Schweizer 333 for a helicopter loop around the grounds.

We arrived back at the core of the vendor exhibits at about 6 pm, just as tens of thousands of people were walking back from the flightline where they’d been viewing the airshow. The legacy piston airplane manufacturers, Piper and Cessna, had shut down their booths and gone home. Tens of thousands of potential customers streamed past, some stopping to look at the parked airplanes but there were no salespeople to answer questions. The Cirrus booth, on the other hand, was fully staffed and engaged with the eager public. It is not hard to understand how Cirrus took 50 percent of the market away from the legacy companies.

The traditional Oshkosh mishap starts with a guy spending three years in his garage building an airplane. During this time he does not practice flying because he is busy turning wrenches. Anxious to show off his newly completed aircraft, he gets in the plane in North Carolina and embarks on his first real cross-country flight. The plane is wrecked at some point during this trip, though not always at Oshkosh itself, which has long wide runways. This year was a little different, with a $6 million Beechcraft Premier jet pancaked into the ground and split in half (story). Fortunately both pilot and passenger seem to be recovering well.

Oshkosh is not short on infectious enthusiasm. Hundreds of thousands of people come to explore their dreams of flight. Hundreds of startup companies set up booths to show off their wares. This is a market strangled by government regulation and, at least in the U.S., clouded by the economic depression (the sectors of the U.S. that the Politburo has favored in the latest Five Year Plan are government, Wall Street, and health care, none of which are natural users of light aircraft (government folks can stay in their state or in Washington, D.C.; doctors can stay in their hospitals; Wall Streeters mostly stay in Manhattan or head out to Shanghai; a regional real estate developer or retailer would be a natural customer for a light airplane)). Yet entrepreneurs show up with a fiberglass mockup saying “we expect to be certified in 2-3 years” and “we just need to close the next round of financing”.

Some energetic young people from Korea showed up their new four-seat airplane, to be certified in two more years. The plane is made of plastic, exactly likely a Cirrus SR22. It has four seats, exactly like a Cirrus SR22. It has a turbocharged Continential IO-550 engine, exactly like one version of a Cirrus SR22. I asked how much it would cost. “Less than $700,000,” was the response. So the plan is to make a virtual copy of the market leader’s airplane and sell it for the same price. In what other industry would people persist with this kind of plan?

An industry veteran in a new company (he’s a friend so he’ll remain nameless) was kind enough to talk to me about his new company. I asked “Not to be rude, but who would be stupid enough to invest in a yet-to-be-certified design? Think of the risks of the plane being delayed by the FAA and then the risks of liability once the plane goes out the door.” He challenged me to name an investment that would be lower risk. I said “Pizza Hut franchises in Brazil and China.” He replied that a Pizza Hut would face competition from local restaurants and therefore an investment in his company was far safer.

The company that might change the industry is ICON Aircraft. The PR, Web site, brochures, and industrial design are all competitive with what an automobile manufacturer might accomplish. If you called up Central Casting and said “I need a square-jawed business executive who used to be a fighter pilot” they would send over someone just like Kirk Hawkins, the founder and CEO. He stood up and gave a talk reminiscent of Tom Cruise’s motivation speeches in the movie Magnolia. He skipped over questions such as “Given that seaplanes cannot typically be operated safely even by 20,000-hour airline pilots, how are your customers going to avoid wrecking all of these?” (30 percent of ICON position holders have no flying experience and are planning to get their Sport Pilot certificate after 30 hours of training and jump in (an idea encouraged by the ICON brochures)) or “What happens when you put the wheels down by mistake and land in the water?” (answer with every other amphibious airplane: the plane flips over and often the occupants drown, which is why amphib insurance costs a lot more than helicopter insurance). The plane/boat costs $139,000 and seats two.

The Achilles Heel of the ICON is that everything is optional, even stuff that you would need such as wheels. This will presumably drive up the cost but more importantly will drive up the empty weight. The “useful load” will be 420 lbs, typically equipped. That includes two passengers, baggage, oars, life jackets, headsets, water emergency gear, etc., etc., and fuel. The tanks hold about 20 gallons and gasoline weighs 6 lbs. per gallon. The legal full fuel payload is therefore 300 lbs. for a two-seater. I predict that this airplane, if it is ever certified as a Light Sport Airplane and delivered, will almost invariably be operated over gross. Therefore the customers won’t be able to rely on any of the book numbers for runway length and stall speed. The engineers seem to have anticipated this and the most prominent instrument in the panel is a military-style angle of attack indicator. This will show how close the wing is to stalling, irrespective of how overloaded the plane is.

Experienced seaplane pilots at the convention did not like the ICON. “For about the same price, I can buy a used Lake Amphibian [four-seat certified seaplane]” they would note. I think that ICON stands a good chance of expanding the market, something that Light Sport has thus far failed to do (mostly Light Sport pilots are ancient guys who are expert certified airplane pilots but who can’t hold an FAA medical anymore).

Air to air photos: flying the helicopter around Boston

Jon Davison came over from Australia back in September. He is doing a book on Robinson helicopter operators worldwide and was kind enough to take some air-to-air photos of N404WT, our first R44, flying over various sights in the Boston area. Enjoy the slide show.

[Tech details for my photo.net readers: Jon was using his Nikon D200 and Sigma 28-200, $240, the kind of superzoom that I have always told photo.net readers not to buy. http://photo.net/learn/aerial/primer shows some images taken with standard Canon lenses (taken by me when I wasn’t busy flying the helicopter in formation).]

Some news from Oshkosh

My summer of travel precludes a trip to Oshkosh, Wisconsin this year for the big fly-in, but some interesting news is filtering out. Aspen Avionics will be starting sales of a glass cockpit for older certified airplanes costing between $15,000 and $25,000 (installed) for a complete set of instruments that will fit into the holes formerly occupied by mechanical gyros. This is less than half the cost of existing systems from Garmin, for example, which also tend to require more reengineering of the airplane’s dashboard. The primary flight display, showing attitude and heading, is about the same price as the mechanical instruments that it replaces.

In other news, Eclipse Aviation ripped one of the engines out of its very light jet. The new single-engine plane will enjoy a lower price, longer range, slightly slower cruise speed, and the same 41,000′ service ceiling to get above weather.

The Light Sport category of two-person airplanes heated up. Cessna revealed details of its 162 SkyCatcher, which will be delivered late in 2008 with a glass panel at a cost of $109,000. Full fuel payload, at 346 lbs. (stripped aircraft, presumably, with no options), will be inferior to the 1995 Diamond Katana. A good plane for anorexics. Cirrus, which has been slowly taking away all of Cessna’s piston-powered business, will be in the Light Sport market slightly earlier, with a product adapted from a design already certified in Europe.

I wish that I had voted for Ross Perot…

I had an antipathy to Ross Perot, the independent presidential candidate, from the moment that I heard him speak on television.  He was talking about education.  Any time that you hear a federal candidate talk about education you know that he is trying to snow the voters.  The Federal Government has almost nothing to do with funding or delivering education in this country; it is overwhelmingly a local and state government show.


But it turns out that H. Ross Perot, Jr.is my new hero.  I was down on the Washington Mall on Sunday afternoon.  The Smithsonian was running a folk festival.  Instead of scheduling it from 5-10 pm, Mexican- or Italian-style, they’d scheduled it during the peak heat of the afternoon.  After one hour it became intolerable and I ducked into the Air and Space Museum to soak up the air conditioning.  Up on the second floor, they have a Bell Jet Ranger helicopter.  H. Ross Perot, Jr., a young punk with 500 hours, and J. Coburn, a 3500-hour Vietnam vet were the first people to fly a helicopter all the way around the world.


Two guys.  Big extra fuel tank in the back seats.  One (very reliable turbine) engine.  Refueling stop on a container ship.


(I’ve not kept up with the achievements of the children of our current President; perhaps the comment section will fill up with reports of their heroic deeds.)

Privatization of Air Traffic Control

Measured objectively, the government sector of the United States runs some of the developed world’s worst-performing schools and the best-performing aviation system.  Yet oddly enough it is the air traffic control system that politicians propose to privatize.


Privatization is currently underway for flight service stations.  These are FAA employees who don’t separate airplanes from each other but instead provide varied forms of assistance.  You can call Flight Service on the telephone to ask about the weather before departing.  You can call Flight Service on the radio to ask where the thunderstorms are along your route or what the closest airport with good weather is.  You can call Flight Service in an emergency.  These folks are incredibly resourceful and helpful by and large and often go far beyond their job description in an effort to help pilots.


The folks at www.naats.org are trying to save their jobs and they’ve put together a very interesting audio clip that is worth hearing whether or not you care about this issue:  http://www.naats.org/docs/flightassist.mp3 (you may decide not to fly with beginner private pilots after listening to these emergency calls).


Plan for today… fly to Republic Airport on Long Island and swim in Bob’s pool, then back to Bedford and over to the Weston Town Green for a 7 pm concert by Not the Beatles (the infamous Luke, of Harvard Square fame, is lead guitar).  The concert is free but bring your own blanket and picnic.  Alex will be there!

My first helicopter lesson

Due to a large number of fatal crashes during training, students are not allowed into a Robinson R22 2-seat helicopter, even with an instructor, until they’ve had some ground training.  If you believe that you have some special mission on this planet the grounnd training might cause you to terminate your.


Here’s what I learned about the hazards inherent in flying helicopters…


As with airplanes, the key to being safe in a helicopter is energy management.  In an airplane you have potential energy (altitude) and kinetic energy (forward speed) that can be traded off against each other to bring the airplane down gently in the event of an engine failure or ordinary landing.  The helicopter has three kinds of energy:  potential (altitude), kinetic (forward speed), and angular momentum (blade speed).


In an airplane you can make decisions about trading forms of energy very late in the day.  For example, if you pull the stick all the way back at 6000′ above the ground you will gradually slow down and eventually stall and perhaps enter a spin.  With many airplanes you could spin nearly all the way to the ground before applying forward stick and opposite rudder to get back to a normal flight condition.  All without an engine.


In a helicopter, by contrast, if the blades spin down more than 10-15% from their normal velocity, there is no way to convert potential or kinetic energy into spinning such that the helicopter will start to fly again.  If you don’t have an engine, therefore, your helicopter can very quickly become a rock.


In a turbine-powered helicopter like the Jet Rangers that are typically used for sightseeing the blades are heavy and the blades won’t slow down for several seconds after an engine failure.  The Robinson, however, is designed for super high efficiency and therefore everything is as light as possible.  After an engine failure you have no more than 1.2 seconds to take exactly the right actions or the helicopter cannot be recovered.


What if you do take all the right actions?  Suppose that you’re up at 4000′ and the engine quits.  You lower the collective pitch (lever on your left) immediately to flatten the blades and allow them to be driven by the wind through which the helicopter is now falling at 2000 feet-per-minute.  You adjust the cyclic (stick in front of you) for about 65 knots of forward speed.  You aim for a landing zone.  The good news is that you don’t need a very large one but the bad news is that the glide ratio is 2:1 instead of an airplane’s 10:1 and therefore you don’t have as large an area from which to choose.  As you get within about 50′ from the ground you pull back the cyclic to flare the helicopter and shed most of the forward speed.  Just as in an airplane this flare also arrests most of the vertical speed.  At the second to last moment you stop flaring and return the helicopter to being parallel to the ground.  Ideally at this point you are hovering 5′ or so above a soccer field and the blades are still spinning.  Finally you raise the collective as the helicopter falls, using the stored energy in the blades against the force of gravity.  You land gently on the skids.  (In practice the cyclic flare is more important than the “hovering autorotation” at the end; a lot of people walk away from helicopter engine failures if they get the cyclic flare right but can’t manage to pull the collective smoothly at the last moment.)


This all sounded good until we looked at the “deadman’s curve”.  The marketing literature for helicopters says “if the engine fails, you can autorotate down to a smooth landing.”  The owner’s manual, however, contains a little chart of flight conditions from which it is impossible to landing without at least bending the helicopter.  Unfortunately these conditions are the very ones in which nearly all helicopters seem to operate.  If you’re above 500′, for example, you’re pretty safe.  But TV station helicopters are often lower than that when filming.  Flying along at 65 knots is also good but if the camera needs the pilot to hover the helicopter slows to a crawl.


After a couple of hours of theory we went to the hangar and preflighted the helicopter.  The engine is flapping in the breeze on an R22 and therefore you can inspect a lot of linkages and lines that are hidden on most airplanes.  Most of the other critical mechanical components are open to the air or accessible via covers that you open during the inspection.


Four hours after the lesson started we were ready to fly…  but the ceiling was 900 overcast with visibility 4 miles in mist.  So we gave up and went home.

Flying in Israel

Spending a few days on Martha’s Vineyard listening to birds chirp, waves break, golfers golf, and … airplanes flying overhead at all altitudes and in all directions.  Quite a contrast from general aviation in Israel, where I did two flights last week in Cessnas.  [Snapshots at http://www.photo.net/philg/digiphotos/20030606-g3-israel/.]


Every American pilot ought to fly in Israel, if only to see just how
bad it is likely to get as the U.S. suffers from more terrorist
attacks.  Getting into a general aviation airport is very difficult.
You have to explain who you are and why you need to fly.  In 2000 and
1992 Israeli security officials lost interest as soon as they figured
out that I was a native-born U.S. citizen.  Attacks from Muslims born
in European countries, however, have turned the Israelis into
xenophobes.  If my host/pilot hadn’t been friends with the chief of security
for all airports in Israel, I wouldn’t have gotten into the parking
lot much less an airplane.


Once you’re seated in the plane the security remains just as tight.
You make a radio call to request permission to start up the engine.
You make a radio call to activate your previously filed flight plan.  Unless you’re coming in on an instrument flight plan from a foreign country, everything happens in Hebrew.  It is basically illegal for anyone without an Israeli license to operate an airplane, or even touch the flight controls without an instructor on board, under VFR within Israel.  This is partly due to the fact that the controllers aren’t accustomed to working in English but perhaps more due to the complexities of navigation.


Once in the air the entire airspace of Israel is forbidden except for
a handful of designated VFR routes and altitudes, which are not in a
standard GPS’s database.  Even though the controllers have very good
radar coverage of the entire country you make regular position
reports.  If you deviate more than one mile horizontally from any of
these routes the controllers will chastise you; keep in mind that the
State of Israel is only about 10 miles wide in the middle–if you get
off course you will be straying over the West Bank and the government
is afraid that Arabs will shoot at you.  In the good old days you
could fly down the valley of the River Jordan, land at the Jerusalem
airport, fly over Jerusalem, etc.  In 2003 all of that is closed off.
With virtually nowhere to go it will presumably be time to land soon.
If an airport closes at 5:00 pm, it is forbidden to land after that
time.  There is nothing like the pilot-controlled runway lighting that
is standard in the U.S.


Safety ought to be better in Israel than in the U.S.  The weather is
almost always clear.  In the U.S. you may depart from New Jersey in a
small airplane and arrive several hours later in Maine to completely
weather that is completely different from what it was in NJ, from what
it was in Maine when you took off and got a weather briefing, and from
what was forecast.  By contrast, the whole country of Israel is no
larger than New Jersey and the weather tends to be very similar across
the whole landscape.  In any case you take off and land at the same
airport most of the time, usually flying for less than one hour.


Mid-air collisions only constitute a few percent of the accidents in
the U.S.  Nonetheless they seem even less likely in Israel because all
airplanes are on designated routes at designated altitudes in radio
contact with and under the control of air traffic controllers.


In the U.S. an airplane operated privately has to be inspected and
recertified airworthy by a merchanic every year.  An airplane operated
commercially, either by an airline or a flight school, needs a
mechanic’s inspection every 100 hours.  In Israel an airplane has to
be inspected and certified airworthy every morning.  A mechanic walks
out onto the flight line and signs off all the machines that are going
to fly that day.


One thing that is very odd about Israeli pilots is that they are not
trained to lean (adjust the fuel-air mixture to compensate for air that is thinner due to heat or high altitude; your car does this automatically but little airplanes generally run on 1930s technology). 


They taxi full rich.  They take off full rich, even
when it is 40 degrees C (over 100 F) outside.  They cruise full rich,
unless they are over 3000′ MSL.  They really ought to all have died
from either fuel exhaustion or failure to climb when fully loaded on
very hot days.  The performance and range figures in a Pilot’s
Operating Handbook (“P.O.H.”, the owner’s manual that comes with the
airplane) are calculated by American pilots using American procedures,
which include leaning very nearly to peak exhaust gas temperatures.
Most Israeli airplanes are ancient Cessnas that don’t have fuel flow
gauges but it seems safe to estimate that Israelis are using 50
percent more fuel than would be predicted by the P.O.H.  Probably what
saves them is that the distances are so tiny; you could fly almost
anywhere in Israel from Tel Aviv using only what an American pilot
would keep as a fuel reserve.  For climb-out at a high density
altitude Americans who fly in the West learn to find a peak power
mixture setting on the ground and then richen just a bit for cooling.
Perhaps what keeps Israelis alive is the near sea level elevations of
all the airports here and the fact that the terrain isn’t very
dramatic, i.e., you never have to climb very steeply to clear a hill.


Oh yes, and the hourly rates for all of this are about double that of what it costs in the U.S.

Weekend in Gettysburg

Richard and I flew down to Gettysburg, Pennsylvania over the weekend to visit his brother, a professor at Gettysburg College.


On the way down we stopped at the Kingston-Ulster airport and were picked up by Richard’s friend Annie, a flying kinetic whirl of activity whose mass could only be characterized by a probability distribution.  We drove a few miles to Bard College’s new auditorium, designed by Frank Gehry.  From the air this had seemed like a misshapen metal-clad lump.  From the ground it still looked misshapen but not ugly.  It cost $60 million to build.  Running a not-for-profit college would seem to be a very good way to accumulate cash.  Even after spending $60 mil the school had enough money left over to pay lots of security guards.  A performance was in progress in the small theater and every door was locked and guarded.  Annie was not be deterred.  We walked around the back and walked in the stage door with the members of the Charles Mingus Orchestra, unchallenged past the security guard who was reading a book.  Lesson:  never hire a hippie college kid to work security.  The main theater did not impress but the backstage was amazingly huge and intricate.


While the local swells attended a play the students played Frisbee and sang folk music in front of the Student Center.  Posters advertised a show of “Palestinian Art; Four Decades of Response to Oppression” (with the world’s fastest-growing population (5% per year) and most of their money being siphoned off by kleptocratic rulers perhaps the Palestinians are now going to support themselves via indigenous arts and crafts).  We walked past the booths selling tie-dyed clothing and through the campus until we arrived at a mansion on the Hudson River, complete with formal garden.


After a late lunch in Rhinebeck we got back into the DA40, bound for Gettysburg.  We flew up a beautiful river valley that crammed together an enormous open-plan new prison, an enormous fortress-like old prison, a golf course, and a scattering of McMansions around the fairways.  We followed a ridge of uplifted hills, cut through by rivers and highways, then climbed to a more efficient altitude of 6500′.  We passed near Harrisburg and over the Three Mile Island nuclear power plants (two cooling towers dead; two blowing steam) before landing at the Gettysburg Airport.  This airport is right next to a mobile home park in which you could buy a nice trailer for $20,000 then rent a hangar for $200 per month.  All the convenience of an airpark without the expense!


The Gettysburg battlefield park is one of the best-preserved and most interesting among those in the U.S.  This was the pivotal battle of the War of Northern Aggression (know to the victors as the “American Civil War”).  The Southern armies under General Robert E. Lee had come to bring the fight into the North and were briefly in a position to reach the big cities of the Northeast.  After the South went home on July 4, 1863, the outcome was inevitable.  This was the first time that artillery, the rifle, and the digging of trenches came together to give the defense a huge advantage.  The Civil War was thus the first modern war in terms of tactics, in terms of press coverage (photographers were embedded with the troops), and in terms of the total mobilization of industrial civilian economies.  The offense did not gain the upper hand until Hitler’s air power, tank columns, and mechanized infantry conquered Europe in the 1930s and 40s (we’re still in the “offense wins” epoch of war, apparently, if the invasion of Iraq can be considered typical).


[To see what an improvement in political leadership can be achieved via professional speechwriters and Microsoft PowerPoint, check out the Gettysburg Address (original and improved).]


Being a professor at Gettysburg College seemed like a lot of fun.  First of all, even on a professor’s salary you can afford a large newish house on several acres of land, typically part of a recently subdivided farm (subdividing farms is to this decade what day trading was to the 1990s).  Now that you’ve got the big house you can start throwing parties for your colleagues.  Most of them will show up because there isn’t much else to do in Gettysburg.  Thus your life consists of going from one party to another, mixing with academics from every area of inquiry.


[Why doesn’t this happen at MIT?  First, the young fun people who work at MIT can’t afford to live anywhere near the school unless they want to cram themselves into a studio or 1-bedroom apartment, not suitable for parties.  Second there are all kinds of social and entertainment opportunities in a big city like Boston.  Third, there are too many professors in one’s own department to get to know and therefore one is unlikely to be coerced by circumstance into socializing with people from other fields (the EECS department at MIT has more than 150 faculty).]


Having soaked up the scenery and the smell of the apple blossoms it was time to depart this morning.  We were greeted by a dreary mist, clouds hanging on the hills, and a steady rain.  Flight Service said that the warm front was coming through sooner than expected but that the weather was clear to the northeast.  Richard and I departed under instrument flight rules (IFR).  This is a bit tricky at an airport with no control tower and no radio repeater for the air traffic controllers (ATC).  You need to take off and gain altitude before you can talk to ATC but it isn’t safe, prudent, or legal to climb into the clouds unless you’ve already talked to ATC.  We picked up our clearance with a cell phone call to Washington Center from the airplane as we sat on the ground in Gettysburg.  They cleared out the airspace north of Gettysburg for 10 minutes, giving us enough time to depart (if we’d had a problem taking off we would have called them back to cancel).


Despite a headwind, we were on the ground in Boston 2.75 hours later.  We had climbed up to 5500′ and never entered the clouds.
