How do lightsabers exist, why do ships fly like they have air resistance in space, how come we can hear laser blasts and engine roars in space? You are still bitching about a half second clip when there is so much shit that doesn't make sense in Star Wars.
If you are still hung up on it. Please relay to me how this gravity works on Star Wars ships. Do you have the specs? How do you know where the center mass of the ship is? Why would the gravity be focused just under the seat? Are you sure that this particular fighter didn't have issues with it's gravity field? Or maybe it could have been a design flaw. Maybe it was because of the ships modifications. maybe it was the huge asteroids they were flying through.
