Don't concentrate so much on the specific jet/prop/helo. It's not up to you, even if you're a natural in the top of your class. If there's not a slot for platform X available the week you finish primary, then feel free to pick door #2...or #3. Likely you'll get a "congratulations - this is what you're getting."
If you're in it just for a specific plane, you're not in it for the right reason. You're an officer of sailors, marines, whatever, first - and a pilot or NFO second.
