Oh yeah, if you do find yourself in a bit of a mess in the slot, remember rule number one of the Hitch Hikers Guide.
DON'T PANIC!
Cut your throttle back to zero.
If you have landing gear out, pull it back in.
Either use your thrusters to try and position yourself into the center of the slot and then proceed if clear or
Put the ship in reverse and pull yourself back out of the slot and line yourself up again.
Try and do so as calmly and gently as possible.
That's another thing - it's not only bad enough I drifted up, but the fact that I couldn't get out was (literally) the killer.
I tried all of the above - none of it worked. It was like the ship was welded to the ceiling - down thrusters didn't do a thing - nor reverse thrusters.
It wasn't the damage of hitting the ceiling that killed me - it barely put a dent in the shields - it was that I couldn't get out of the letterbox and after 90 seconds - the station opened fire
And this happened twice in a row
