In SFB-ese a ship can loose control if all it's control spaces are destroyed. And where Star Fleet Battles rules are for Star Fleet Battles, if you really need something in a pinch, you could template loss of control effects into your ACS starship combat damage.
I always figured you could "pilot" a Traveller ACS from engineering, albeit badly. Landing in a standard atmosphere with heavy battle damage might be "Impossible" task wise, but a skilled group of players might give it a shot.
If all else fails someone could reroute (hack) the ship's flight controls through a player's phone / hand held comp.
Imagine sitting on the deck holding your phone like a gameboy trying to land, and all of your fellow players' characters' lives are dependent on your character's ability to play some flight sim.
