If you get close enough to a ship to crash your plane into it, why not just use a bomb instead? You can drop the bomb from altitude, do damage, and stand a chance at getting away. Seems silly in that respect. On another level, it'd be used to game the game.
"Hey, let's get 20 guys to kamikaze the hangars and town, then rush the goon in!" or "Hey guys, let's go out and kamikaze all the tanks at this camped spawn!"
Nope.
