Mogus,
I know most of the replies here are from Air Force types, but there is an option to fly Army as well. I'm a West Point guy and now a UH-60 Blackhawk pilot. Although Ill probably get out at the end of this year, I wouldn't trade my experience at West Point and in Army Aviation for anything. I even started my civilian flying while I was at West Point in the Flying Club and had a blast while my other Plebe buddies were stuck in the barracks, I was flying all over NY, NJ, CT, Mass., etc.
The good thing about the West Point / Army route is that not everyone there wants aviation like at the other academies. If you end up in the top half of the class, you will definitely get it. Flight school at Ft. Rucker is a lot of work, but a LOT OF FUN also. Granted, it's definitely a different kind of aviation, but it's great! Air Assaults at 120 kts on top of the trees at night under NVGs one disk from the a/c in front of you and behind you is quite a rush.
As for me personally, I've been there, done that, I'm ready to move on to airline flying and have been working at that for the past couple of years on the side. I now am approaching the hours needed and experience to at least get into Part 135 and hopefully into the regionals.
This path is certainly not the fastest way to get there, but it's probably one of the most rewarding and you will have a degree from one of the finest schools in the country. If flying ever falls through, trust me, you will have no problem getting a job anywhere.
You are definitely doing the right stuff. As others have said, keep up the sports, continue doing some volunteer work, focus on your grades, take some higher level classes (AP courses, etc.). Also, get into some club or something where you can run as President or "on the board" or something like that. It shows leadership and they love that. If you want some more detailed info, shoot me an email and I will be glad to help you out.
Keep up the good work and let me know if you need anything. Good luck and keep pressing on!
Peter
