Question. In STiD, Enterprise is falling to her death. Scotty says the warp core is out of alignment and that the ship is dead. Kirk fixes the core and Sulu arrests the big E by... Wait for it ... Firing thrusters??? Why does Enterprise need warp power to fire thrusters? The most you need is wiring, some control circuits, the thrusters themselves, and a bit of aux power to run the whole thing, which they early had... The lights were on. In ST09, Sulu abandons Warp AND impulse and lifts the ship using thrusters alone.
