Had to think for a second, I kept saying to myself hangar map?? I think someones gone crazy but I was wrong. I came accross the video your talking about. It doesn't show much, just a few shots here and there. Looks like it was suppose to be a CTF or Assault map.
Gamers Hell has it.
Gamers Hell RC Game Play Movie
And a few screens I took from the movie.
Another shot from the hangar map?
