Hi Harry,

WAY back then, just getting airborne and back down again
safely would rate it as a 1.

Times have definitely changed....

Thanks. I was not quite sure what order some of them were to go in, With

Richard,

Now that you mention it, I guess it was the #1 of its day. After all,
it could both bank AND turn! Imagine that! Of course, every other
flying machine of the day was a 10+.

Makes me wonder where a Gee Bee rates on the scale though.

I think that would depend on who is flying the Gee Bee.

Doolitle managed to fly it and survived, but he was about the
only one (back then). I always suspected it had something
to do with the pilot(?).

Actually, the Gee Bee isn't all that bad. Better than my old Stits
Playmate! It had a top speed in level flight of 110 mph and the first
indication of an approaching stall was an uncontrolled snap roll to the
right at 98 mph! I had to dive down final at full throttle in order to get
Vso + 30 % that they recommend for approach speed! :-)
