All aircraft are structurally capable of doing a 1G barrel roll; if done right it stresses the aircraft no more than level flight. the B707 pilot said so himself in the original video. No Boeing or Airbus will ever do that again and the 707 pilot got a WTF are you doing from his boss. Didn't any of you see the original video? Don't any of you know what a 1G barrel roll is? The stewardesses can continue to poor the champagne during a 1G barrel roll. Do you think Airbus makes their simulators behave differently from the real aircraft? That would be stupid, and thinking they would do so is silly.
