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.
Factual error: In the scene where Joe Patroni is attempting to move the stuck 707, Bakersfield 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.
Other mistake: When the stricken airliner is on final approach for landing, both pilots stare intently out the windscreen, never so much as glancing down at the flight instruments. In an instrument landing the pilot must look continuously at the instruments until the copilot reports that the runway is in sight, as that is the only way he can follow the controller's instructions.
Question: First there's a scene showing the "Golden Argosy" flight crew taking a mini-bus out to the plane (which, I assume, is already at the gate). The next scene shows Vernin Demerest and Gwen Meighen alone on the plane talking about her being pregnant, etc. Later in that same scene we see the rest of the crew getting onto the plane while Demerest and Meighen are all-of-a-sudden pretending there's a problem with a light. My question is this: If they all went out to the plane together on the bus where were the rest of the crew while Demerest and Meighen were talking on the plane? Wouldn't the whole crew have arrived together and got onto the plane together?
