Uhh. . .I'm going to have to say no, unless you do some serious revisions. 21 is really too young to be a college-graduate, which is generally required to be a pilot. . .either that, or be prior-enlisted who impressed somebody enough to be sent to flight school. Every military that I am aware of forbids tattoos below the wrist or above the collar. Fighter Pilot isn't a rank. . .it's a job description. Lieutenant Junior Grade (JG) is an appropriate rank for your character. Flying "straight into battle", battle being space, when massive amounts of fire, lasers, guns, missiles, etc, both friendly and enemy, can be coming at you from 360 degrees, is not a good idea. You fly in formation instead, in flights (four), squadrons (12, and wings (36), and you never go anywhere without your wingman tight on your ass. And finally, with the kind of engines that power these fighters, if you did ram another fighter with your wing, likely at very high speed, the explosion would have consumed you, and even if it didn't explode, your shattered wing would send you into an endless roll and probably kill you all the same. Not trying to be mean, but this is a unique RP.
