What you missed are 2 things. First, there is a "thing" between jet and helo guys. I won't really say more since I can't imagine a way to describe it in a non-baised way that wouldn't piss someone off. I will say this and allow you to draw the appropriate inferences: typically, the guys with the highest grades in flight school go jets, while those who perhaps spent a bit to much time having sex with their girlfriends when they should have been studying end up going helos. (says the now-wife of a helo bubba.

)
Second, you don't really select helos in the the same way you select intel. You select aviation and after completing the first part of flight school, based on your grades, preferences, and the needs of the Navy that week, you select/are assigned to helos, jets, etc.
