I think any rated position has an age cut-off of 28 actually.I read an article that said the air force is really in need of aviation candidates. Because of budget cuts, experienced aviators are getting out in droves and the Air Force is offering bonuses to keep them in to the sum of something like $120K for four years. Most of them are getting out to pursue becoming commercial pilots where they can get more air time and make more money. The age limit for AF pilots is 35 I believe.
