So... The consensus seems to be that, apart from one aberration, the physical requirement for fast jet is a small penis. That truckies can't see their's no matter how big it might be and Loadmasters have extremely long and powerful appendages...
It seems that "fast jet" syndrome can be "fixed" by wearing a big watch. Can you imagine how freaking awesome you'd be if you were a Loadmaster wearing a big watch....
It'll never happen I'm afraid... Evolution stepped in and you young types just don't have, or need, the colossal appendages that Loadmasters required so the RAF, in it's wisdom, disbanded the trade. Now they have some amorphous blob trade with merely average penii...
