Dondragmer's continued artistic exploits have uncovered some interesting hand gestures buried in the code of Wing Commander 1. It's likely that these were intended for the mechanic tech that greets each pilot upon landing. Note the blue sleeve versus the brown jacket around pilot hands. A thumbs up might appear if a fighter returned with minimal damage. A less graceful motion could greet the pilot if they've created a lot of work for the crew chief to deal with!
