Yes, I was wondering that. I don’t know if the landing gear is visible to passengers on an A320, but if it is, I would have thought someone would have asked a flight attendant why it was still down after takeoff.....................
The landing gear are most definitely not visible to anyone on board, other than stowaways in the belly. But you can hear the gear being retracted and you can hear and feel the aircraft become more aerodynamic when the gear finish coming up. It’s strikingly apparent if you are tuned in... and when I fly I can’t help but pay attention to every little gnat’s eyelash that happens to make a peep. I should mention.... I HATE FLYING!!!
