@MindfulL205 Not all aircraft are operated this way. The Lockheed L-1011 used a door that opened vertically and was operated automatically by pressing a switch. It did have an alternative manual mode though. I flew them for a few years. it was a fine plane!
@BLackgold_5 Not real, not aerodynamic, and not a thing. Two flight decks? That is a dead giveaway. No way would a design feature two different flight crews operating one airplane.
@historyrock_ I don't care one way or the other about Bruce Springsteen. I used to like his music until he went off the deep end into the woke madness. Now I just ignore him altogether.
@Brink_Thinker They take flight because of a principle formulated by an Italian fellow named Bernoulli. His formulated principle describes precisely why aircraft fly.
