We expect all kinds of nerdery from the folks at NASA, but the Air Force has always been another story, until now. Air Force Chief of Staff Mark A. Welsh recently gave a briefing while wearing this Captain America luchadore mask. He even pointed to the “A” on his forehead and said it stood for Airpower. Yes, I realize Captain America was in the army and that the “A” stands for America but this is the Air Force, not NASA. He gets points for the effort!
