Yes, don't check Nav! I work with a Nav now that wants to be a pilot and he's done nothing but try and try to cross over early and he could've done it if he had the waiver. He didn't get that in and they denied him. Now he just has to wait and try again (sounds like a big pain in the a$$) I also work with a pilot that used to be a navigator, so it can be done. Right now though he's a Capt co-pilot about to go up for his Maj board. I'm just a enlisted FE, but from what I understand it's pretty hard to move to the next level, especially Maj as a Co-pilot. So, try and avoid the whole a$$ pain and just check pilot. As for everyone else out there wondering about going to the desert, I've been in for coming up on 8 years and the only desert that I seen was while I was in New Mexico. It's all hit or miss on what you're on or where you're at and definetly timing. I just went through my AEF at homestation. Although it'd have to pretty improtant to pull us with Uncle Kim and his constant antics.
