Airbus- a map placed inside an airplane. however its large enough to be relatively c4 proof.

two more maps that i think would work but aren't as good in my opinion.
stargate 
the ship

Airbus, I believe, has an exploit, where you can grapple onto the fuselage when you jump out the door.

Stargate was removed for the portal being broken at times.

The ship looks nice, but we already have 3 ship maps, maybe we can remove roy *hint*
