340,000 Pilots Needed For The Next 20 Years?

My brother's stepson went from AFROTC to regular Air Force flight
training. He went the Tanker/Transport route, flying the Beechjet, then
C21(Lear 35) VIP transport for two years before getting a slot for
C17's. C17 training lasted three months. He spent his time in the right
seat before moving to the left. He got out after 10 years as a C17 IP.

How many hours of specific intensive training aimed right at a
specific type rating it would take to make a highly intellegent and
physically qualified person to able to fly with mature ATR confidence?
One measure would be, how long it takes the airforce to train its C17
guys.
