There are a lot of things I see wrong with how the all mighty selection boards determine who is capable of being a military aviator, especially the ROTC selection process. One thing is for sure though, if you are a qualified candidate and you have the determination to go through what you must to get what you want, you will get it. If you are determined enough to be a pilot, mostly anything that gets in your way be it medical, getting selected, or whatever will be just that - it's not the end of the world.

It basically compares the different selection processes and the cites the incredible differences in the way they evaluate candidates.
