I tried searching for this bug to see if it had been posted here before, but there's no sign of it. If you guys already know about it, I apologize in advance. I just discovered this today, and was advised by PPK to post about it here. First, basically by standing in front of where the wall doors slide open upon activating the switch to extend the bridge...you can actually have the doors stay closed with the bridge drawn out.

Also, we discovered that its possible to stay afloat once the bridge has been drawn, basically by strafing towards the wall.
