Other mistake: During the scenic elevator rescue scene, a helicopter lowers the Fire Chief down to connect a cable to the top of the elevator.

Other mistake: As the rescue copter is lowering down the pilot, it can be seen flying above and in front of the jet so he can enter into the hole above the copilot seat, but passengers looking out of the side windows of the plane can see the copter and that the first guy fails? Not possible.
