Into the Storm (2014)

Factual error: What kind of small American town has an airport that has 6 jumbo jets sitting on the runway? I mean, I think Dallas is the closest airport in the region that would have 4 engine 747s at the ready. Topeka, Oklahoma city, etc. commercial airports could barely handle one 747, let alone 5-6.

Gary: That was good thinking with that knife back there.
Trey: I thought you'd be mad.
Gary: Oh I am. Hand it over.

Trivia: When they are driving the Titus through the town, you can see a cow fly through the air - an homage to the movie Twister.

Question: If the water is blocking the airway of Donnie and Kaitlyn and no one is about to help, how can they survive if they are drowning?
