They were allegedly going straight down at about 10.1 m/s^2, so faster than the acceleration of gravity which makes sense if the engines are running, and somehow some dude crawled to the cockpit, beat up the hijacker, and saved the plane? I think Hollywood just wants to make a cool movie later
Thats acceleration, not velocity. Are you sure thats the right term? But even so, thats only 0.3m/s over normal gravity, so it would be weightless except for about the acceleration you feel when climbing in a plane. But they weren’t straight down Im not saying everything about this is clean, but the physics arent an issue
