You can get a contract to go to flight school as a Marine officer. Look up an officer recruiter, known as an officer selection officer. Most large cities have them. If you have a 4 year degree, 20/30 vision correctable to 20/20, you will be in there with out any problem. You will have to take a test, but there's a practice book at any major bookstore. If the first guy says he doesn't have any air contracts left go to someone else or ask him how many he will have next fiscal year and tell him that you'd be willing to wait until Oct 1st to sign up. You will have to go to OCS for 10 weeks then to another school called The Basic School for six months, then straight to P'Cola for flight training.
That was my route, I've been in the Marine Corps for 9 years now... flew Harriers and currently instruct advanced jet training for the Navy and Marine Corps down in Kingsville, TX.
Bottom line--- there are pros and cons to all of the sevices and all of the platforms, only you can do the research and do what you think you'd enjoy the most.... my opinion is you'll have the rest of your life to fly "heavies" if you decide to get out.... you'll never get to land on a ship, hit a tanker for some gas and blow stuff up in any civilian flying job, let alone know what it's like to hover a jet.... Just my opinion...
