I would much rather have HTC work on a new plane. Can't remember a single time in the past six years that I needed to fly under a bridge.
Haven't used a bridge, HOWEVAH, hangers are great for clearing your six. You get that satisfying BOOM as the target fixated chap smacks into the hanger door.
what if it's an enemy base?
People have done that to me lots of times, I just fly over the hangar and shoot them as they pull up.
