20-year olds flew the bombers that won World War II, at the very least.
I'm skeptical that bomber pilot training really takes 10 years--that seems a tremendous waste in the military. 10 years is half of your active duty career if you stay in the military until retirement.
Well, the other half of WWII ;) Naturally you'd pick a very experienced pilot to drop The Atomic Fucking Bomb, but the average age of bomber pilots over Europe was famously in the early 20's.
