It's being used by analogy with "landing a fish". I've never heard it either, but I could believe it's in the argot of military airmen in some English-speaking country.
It's conceptually the same - having an entity go from water or air to the the ground. The hard part would be to associate the fact that there's no way for an 'enemy' to land the aircraft other than to do so forcibly which implies shooting it down.
