I'm sure you are correct about the difference between individual
tolerance to hypoxia. I recall reading that General Yeager was able
to withstand operating at 20,000' without oxygen.

Nearly all of the pilots in the Great War could. Only some of the German aircraft
had oxygen systems, and I've not heard of any Allied aircraft that did. Ceiling
on the S.P.A.D. was 6,000 meters, according to Nordhoff and Hall.

I must have missed OSH that year. I would really like to see the AN225 and
have always liked the *biggest* anything. Anyway, you might show this:

Jay, you could put your Pathfinder (full fuel, four 200lb people and
baggage), AND the Mighty Grape, AND your motel inside and bring the lot
to
OSH where you could probably get a lot more for your aviation suites.

Yeah, I saw that monster a few years ago -- I think at OSH?

It was parked nose-to-nose with our own C-5 Galaxy -- quite a sight!

That Russian aircraft had better watch the MU2's wake turbulence.

I suspect that the 182's shorter landing performance has more to do with its
better flaps and consequent lower approach speed than with ground effect.

The PA28's flaps are considerably closer to the pavement than the
Cessna's. That might increase ground effect. I agree, that a heaver
load at a higher speed is a significant contributor to the PA28's
longer landing run also.

Perhaps there are errors in the specifications posted:
