I saw that happen with the Marines when I showed up to Meridian. You need to want to be there to tolerate that syllabus. Or at least you did before the Four Horsemen got muzzled.
I know of one guy who DORed because he liked flying but hated aero, being upside down, being in a cramped cockpit, and so on. He picked KC-130s, got forced to go jets, and said "fuck it." What a waste of money.
Honestly, the same way I feel about guys who DOR if they don't get jets, I say the same about this guy. Fuck him. If he can't shut up and color in Jets, he can hit the bricks.
It's easy to criticize someone's choice without knowing the full story or being in their shoes... Those are specific reasons that possibly have some physiological issues driving them instead of him being a stereotypical child attitude from someone who was jaded he didn't get what he wanted. Sounds like the guy knew he'd be miserable every day for the next 10 years of his life every time he flew... more power to him for avoiding that, cutting the military's losses, and not becoming a safety hazard to his squadron mates.
I had an onwing once who was a naturally gifted pilot.
Fast forward a year, he's in kingsville and we're having at one point, discussions several times a week about how much he's fucking miserable and wants to DOR and dreads going flying... why? He got airsickness... every flight... Turns out that besides the few active airsickness episodes he had in primary, he was passively airsick 60% of the flights in the program but sucked it up and flew because he didn't want to get attrited. He gets to T45s, and he's actively airsick, and puking every single flight. Adaptation flights were'nt helping, spin chair wasn't helping, and every flight after BIs he'd be sick...
Would a DOR in that case been a waste of money? Should he have just shut up and color?
