Airport

Plot hole: Petroni has the engines at full power to move the plane out of the rut. Once the plane is free, he never pulls the power back. With that power, the plane would accelerate down the runway until it took off or hit something.

Factual error: When Joe Patroni is attempting to move the stuck 707, Bakersfeld is standing beside his car watching, very close to the plane. Without some form of hearing protection, he would have been very quickly deafened by the noise - a 707 at takeoff thrust is incredibly loud. I once watched a 707 take off from about a half mile away and forgot to cover my ears - it was so loud it actually hurt.

Tanya Livingston: There's bound to be a passenger with a fifty-dollar wrenched back. I'd better get out there with some release forms and plenty of sympathy and understanding.

Question: Near the end of the film, the plane stuck on the ground is pressurised before it can move out of the way. Why is it pressurised if it's on the ground and not in the air?

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.
