It seems silly that there's no way to move a ship in space without using warp or impulse power. Thrusters seem to work with all the computers off, so why not get out using only maneuvering thrusters?
I remember seeing this episode and just being confused by the ending, the thrusters Picard activated worked like a charm and moved the ship in the desired direction. Why didn't they use them in the first place and even if they didn't realize they would work, why did they act like Picard flying the ship out of the trap was a big deal? Oh no, we're not gonna make it ... wait a minute, the captain's using the asteroid's gravity, we'll survive!!! Couldn't he have just used the thrusters to move forward instead of left and right? Shut up, Wesley!
