Factual error: The 747 takes off from Washington D.C., while there's still some daylight, toward the west coast. Due to complications it's diverted to land in Salt Lake City. The Sun goes down and the plane is shown flying all night long. The Sun even comes back up before they get to Salt Lake. Really, how could it take that long for a jumbo jet to fly a measly couple of thousand miles?
Factual error: When the 747 finally lands it makes a hard left turn at the end of the runway. The cutaway to the passengers shows them all leaning to the Plane's left side (due to bodily inertia). For a left turn they should all be leaning to the right.
