The first time I saw this 'chair flying' is the Blue Angels briefing room video[0]. Can they actually remember the whole flow with the drawings etc. and imagine the whole scene with their hand movements etc? Absolutely unbelievable. I've never missed them in all the years since I moved to San Francisco. They're so tight in when they fly and they visualize the whole thing in a chair? Crazy to me.
