check out the Army WOFT (Warrant Officer Flight Training) program... you don't need college to fly rotorwing in the Army...you go to BCT (Basic Combat Training) for nine weeks, then to WOCS (Warrant Officer Canidate School), then to Flight School for about 10 months......commitment is no less than 72 months Active Duty
fixed wing slots in the Army I believe require selection boards if you are not a commisioned officer and you need like 500 TTRW 50PIC to even apply.
RW time doesn't seem to count for much in the airlines.
If you want to go Commisioned Officer through ROTC, you can usually get an Army ROTC scholarship as long as you have a good pulse.
Civilian route:
Regional Airline Pilot is not the pinnancle of aviation careers, don't rush to get there... enjoy flying and building experience. Don't worry about trying to get to regional pilot in 250 hours.... if you read these forums enough.. you'll find that all in all programs like that are a waste of good money... you may be better off going part 61, instructor, part 135, etc - you'll look back to find it a good experience.
