Again, I’m not in favor of short cuts. Military flying has some fundamental differences compared to civilian flying. I am a former T-37 IP with 21 years of flying experience in the USAF. Formation (even heavies do Air Refueling) is one. The pace of training is another - if it took you 75 hours to get your private license in the civilian world - great. That won’t cut it in the Air Force. Aerobatics is another. How many civilians with an instrument rating have been in a spin or legally upside-down, or pulled more than 4Gs? Every Air Force pilot has - multiple times. And then there are the complex aircraft. How many young civilian ATPs have turbine time? The Air Force starts you off in a T-6 on day one. Civilian ratings do not equal military competence.
Certainly there are some civilian pilots with a commercial license and some time in an Aztec who could adapt to flying a C-5 in the required time and be successful. But most would fail - in very expensive training program (aka C-5 school). And not because they are slackers or because military pilots are zipper-suited sun gods, but because the foundational training is different.
Keep the standards high. Those with the desire, talent, and work ethic will meet it. Lowering the bar to make it easier or to “compromise” is a mistake.
