I agree with Stealth, especially the scarcity of getting an incentive ride and that is not only for fighters, but heavies too. Back in Bullet's day the cadets that did get an incentive flight were 9 times out of 10 USAFA cadets doing their summer tour.
Incentive flights are also decreasing due to multiple reasons in my opinion.
First and foremost is as Stealth has said they need them for the FTUs.
On top of that they are using that 1 D model for sorties such as check rides.
Now add on top of this that it costs a ton of money to go up and land, plus taking the pilot away from a mission ready sortie.
~IOWS no fun 4 v 6 red air/blue air, instead let's go up fly around for a few minutes and come back down.
I think when it comes to incentive flights as an AFROTC cadet it is a lot about who you know to get you that ride. You might want to try to get into a sim instead.
