At least for me, I also consider what might happen to me were I to NPQ from SNA at NAMI. Obviously we all hope that won't happen to us, but it happens to some people. If the AF NPQ'd me from what I've seen you become a second class citizen when you aren't a pilot. The Navy has a lot of interesting and varied things outside of pilot that one can go for. Admiral Fallon was an NFO and, from the stuff I've read here, a lot of different jobs are rewarding.

Also, I don't mean to disrespect the AF or anything else. Jesting from winged guys aside (they're entitled), I'm sure the AF has a lot of great and qualified people just like every branch does.
Plus there's also BDCP for the Navy :icon_glas
