Revealing mistake: When the car enters the scene near the beginning of the movie where everyone is getting of the stuck aircraft, you can see the tire track in the snow where the vehicle is going to go. (00:07:50)
Airport (1970)
1 revealing mistake
Directed by: Henry Hathaway, George Seaton
Starring: Burt Lancaster, Dean Martin, George Kennedy, Jacqueline Bisset, Jean Seberg
Continuity mistake: Burt Lancaster is sitting in his car at the end, and he asks the tower if he can listen to the radio traffic for the incoming plane that's landing. The tower replies "Sure, it's on frequency 117.1". Burt then tunes the dial on his receiver to 171, not 117. 170 is blatantly written under the dial in bold type.
Ada Quonsett: When you get to be older, there isn't a lot left to be frightened of.

Chosen answer: Patroni isn't referring to the cabin pressure, he says to "pressurize the manifold" - part of the engine start procedure of a Boeing 707, which I believe involves a ground crew pumping gas (nitrogen?) from a cart into the intake manifold.

Pressurize - as in the manifold, to turn on bleed air from the APU - on board Auxiliary Power Unit - a small jet engine that provides electrical and pneumatic air to operate aircraft systems including starting engines.
