I had a former peer assess after I was about a year into flying there.
Our DAP flight lead did his assessment.
(For those familiar, the short guy that smoked in the cockpit)
My former peer was a West Point grad, had a real cocky attitude (not saying all West Point grads do I know some great ones).
He quit halfway through, before he even hit the part where he would plan, brief, fly.
"It's not for me"
That is the assessment process doing the right thing.
What is unique about the 160th assessment is that everyone goes through it to get in.
Pilots, Doctors, Logisticians, Intel- everyone has to have the same DNA.
