I'm an author and I want to correctly portray a scene (with a bit of artistic license) in my next book. However, I don't think I understand the physics of the situation. Scenario: Passengers flying in a G6 going 450mph at 35,000 feet. Jet goes into a nosedive at let's say a 45 degree angle, wings level. The jet accelerates towards the ground in its fall. What would the passengers experience? Would they tumble toward the cockpit if they were unbuckled? Would they be weightless? Would they hit the ceiling? Would they be forced toward the back of the plane due to the acceleration? Would it be a combination of all of these and more? If so, what would the order be? And, if the jet pulls out of the dive, what would be the forces on the passengers? Once again, into their seats? Heads against the ceiling? Etc. . . . Thanks in advance . . .
