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.
