The MAF doesn't value flying like they should (reference the post that states flying is the #18 priority on a Wing slide-show).
Most of the cross-flow guys are good dudes, but the problem is they show up to the unit as a new AC in their new MAF airframe, fly for awhile, and do an in-house IP upgrade. Their office jobs don't allow them to focus on the in-house IP upgrade. After they become IPs, the office doesn't let them fly enough to be proficient instructors.
With that being said, I am sick and tired of the heavy versus fighter argument...and the C-17 jokes are getting old. It doesn't matter what the fvck you fly, fly your damn jet and hack the mission.
Like Hoss said, "what happens to guys that wash out of a fighter FTU?" They go heavies. Get over it. Granted, some dudes may have had issues in UPT and that they are now crushing their current MWS, but overall the UPT system seems to work well. Timing and luck are definite players in what you drop out of UPT, but tracking -38s and graduating at the top of the class definitely increases your chances.
Now, I'll go back to flying my KC-135 auto-pilot off, into the sun driving directly towards my receiver while shark-finning the tail in IMC.
