In May of 1986, I did my USAF 1.5 miles in just over 11 minutes. The military accepted folks with flat feet back then.
They still do. They also take people with really, really bad eyesight; I just had to get a waiver.
Best PFT was 21 something. I did better at PFT's than group runs, tho. I hate hate hate running in formation. Maybe it's because I have no rhythm, but it's a constant series of falling a couple feet back then sprinting a couple feet to catch up. Exhausting.
