If you do get selected for ENJJPT, do you have accept and if not, does it look bad if you dont? The only reason I could see why you wouldnt want to accept is that you are now competing with the best of the best (Movie reference) which could be mean that while you may be a top 5 in UPT, you could be ranked #10 at ENJJPT. I guess it didnt matter when everyone was guaranteed a fighter\bomber spot, but now it could make a difference
This may be a minor point, but I have seen this sentiment before and I would like to comment on it. While ENJJPT does have a slightly different syllabus then other UPT bases, it does not mean they necessarily produce better pilots. Getting accepted into ENJJPT, while it is an accomplishment, has zero reflection on that individuals ability as a pilot. #1 out of ENJJPT does not mean they are a better pilot then #1 out of Vance/Laughlin/Columbus. It means they were number one in their respective class at their respective base.
I have known people who applied to ENJJPT, got accepted, and turned it down. Why? Because they realized it is not what they wanted. Once you get wings, no one really cares what base you went to. They only care how good you are at your job.
