Sounds like people are not flexible enough to adjust to a new, different environment/culture. I think it's only in the States where if you screw up, the instructors pat you on the back and say, "that's okay, you can do better next time..."
So my question is, why are so many people failing out? I was told the interview weeds out all the applicants who weren't either proficient in their flying skills or people who the interviewers thought did not have the flexibility to readjust to a new cultural environment. What do you mean they grab and yell at you? Are you sure? I know they hit you with a stick then yell at you in that part of the world....
For the guys over there currently, is it worth it over there, with only 10 days off, on the other side of the world - given the current job markets out there in the States or elsewhere?
Anyways, good luck out there.
