maybe if there's more than one person in it, then you can team kill it, although you can't damage from the inside? i'd like that :D
very annoying when bombing, when it hits the plane you're using to fly, or when you shoot a rocket, and it spawns behind you and blows you up
i would like it to still be able to be blown up by their team, only if there is one or less people in it, to respawn it when it's out and done using it, or when they're being an idiot and flying off by themself and wasting a plane
