Zooming past our right wing was Doug Rozendaal and the P-51C Tuskegee Airmen. A P-51C's top speed is around 505 mph. The top speed of the AT-6 is 205. The top speed of the Stearman-- 104 mph.
Hmm. I guess the real question will be, how slow can Doug safely fly the P-51 while still flying in some sort of formation with two other airplanes?
