Factual error: Early in the movie when the interior of the downed aircraft is shown (underwater in Chesapeake Bay), with the eerie picture of Dutch's wife and the congresswoman's husband sitting underwater in first class with their hair waving slowly in the current, they are shown on the right side of the aircraft (the left side as we are looking at them, but the right side of the plane proper). Yet, when the airline representative is discussing this "problem" (non-married-to-each-other people apparently flying as a couple), they are announced as sitting in row X (don't remember), seats A and B. Aircraft seating is always done from left to right - i.e., the A and B seats would be on the other, or left, side of the aircraft.

Continuity: Midway through the film you can see the Washington Monument in the background with scaffolding for it's resurfacing.  Later in the movie the scaffolding is gone.   Yet the movie was released while the scaffolding was still up.
