There were a couple of retreads going through when I went through. They were treated a little better partially due to rank but mainly due to the fact that they didn't need to be treated like your standard new guy. There is a reason why you don't hang with the IP's and you have to call them sir by the way. One P3 NFO had 1500 hours flying civilian, rocked the program and got his first choice E-6's. One guy did alright and got E-2's. Not sure what the earlier post was saying about their jet slots coming from a different allotment, I don't think that is the case. Anyway, fast forward to advanced in the T-45. A couple of NFO to pilot types didn't make it through. So maybe one could say they're previous experience helped in primary but once you get to the 45, there isn't near enough room for subjectivity. A little but you can either land on the boat or not. If not, your double anchors and railroad tracks can't save you. DITTO on the fact that they've earned it. One thing that I've kept in mind over the last couple of years is that there are tons of NFO's out there that would be SH pilots but didn't have the eye sight. They get PRK in the fleet, kick ass on all their fitreps and compete for a slot (usually less than 10 spots a year). I'd treat those guys with mucho respect and get a feel of what the real Navy is like from them, learn from them and work with them. Remember they've been through a training command program, they'll tell you how to play the game. Don't sweat the jet slots, work together, work your ass off, don't hold grudges, work your ass off, help the other dudes around you, and did I say work your ass off....
Good luck and have fun.
