I am a senior in high school and I was accepted to the Air Force Academy.  I can tell you that your chances are looking good so far.  YOU MUST keep up the good grades.  Academics is the most important thing in the selection process.  Take the most challenging courses possible and get an A.  At the same time, be involved in as many things as you can.  I don't think you'll be going in to the academy pilot or navigator qualified.  There might be a waiver for your eyesight later though.
