Can someone elaborate on UPT? What is it and how do you apply to get in? Do you have to be in the military before applying? As the OP asks, how do you know you're going to fly before signing part of your life away? I don't know much about the process so I don't want to make a mistake on paperwork somewhere and sign away 5 years of my life just to continue to stare at the sky. Also I'm still in college, do you suggest I join now or after graduation?
