Age of Wonders: Planetfall by Triumph Studios

Dumb question of the day: I’m in a skirmish campaign as vanguard. In recruiting a gunship I’m faced with a question: how do you repair it? I know you can mod it with nanite injectors, but what I was wondering is it repairable by engies (I assume not since they’re on the ground and this thing is in the air) or perhaps the PUG can do it once for any member of the team (mechanical or humanoid)?
