T-6s are the basis of everything that I do. They are always obtainable, always at the events, and they're affordable. They only burn thirty-five to fifty gallons an hour, at two dollars a gallon, four dollars in England. When I fly with Eddie Van Fossen, who has won the Reno Air Races seven times, we work at 180-190 mph. If the air is bouncy, there's no point in even going up.
Smooth air is essential.
As for physical discomfort, I get air sick terribly. I do have a special pair of glasses that have the lenses screwed to the frames. And that's the one that I show. . I like to go up really early or really late. But there is a point where really early is too early, and really late is too late.
