The problem is, if you are still interested, and if I am correct, is that the ship is suddenly experiencing a massive,
massive acceleration and deceleration.
My understanding is that while your DGIV is attached to the elevator, it still believes that it is wherever it was before. So
when it is released, it updates it's position, and for the briefest of instants the acceleration (the "G force") upon the
ship, according to the ship, reaches a quite insanely high peak. Cue bits breaking off the ship.
