When Dean and Sam pull up to the girl's house, the Impala's wipers stop up on the windshield when Dean shuts it off, but they're down into their normal, parked position in the next shot.

A partial news report states a "transatlantic flight" from Dallas to Louisville was diverted. This is impossible, as Louisville is northeast of Dallas and the flight path is inside the continental US. A transatlantic flight would have had to cross the Atlantic Ocean, hence the name.
