Plot hole: In the mine shaft, with the lift going the speed it does, it would take over 10 minutes to travel 2000 feet. Yet our characters manage to do it in about two minutes (use the bomb timer for reference). With the bomb timer starting at 30 minutes (not to mention Travolta puts it down to 13 in a later shot), everyone in the mine should be dead before they could escape.
