Corrected entry: Early in the flight, one of the pilots explains to a flight attendant that regulations require that if either of the pilots leaves the cockpit, the remaining pilot must put on his oxygen mask until the other pilot returns (which the remaining pilot is shown doing). However when the bomb goes off with one of the pilots in the rear of the plane, they immediately switch to the cockpit and show the remaining pilot quickly putting on his oxygen mask (which he was not wearing) as he puts out the "Mayday" call.
Corrected entry: When the bombed plane lands, the pilot pulls the throttle all the way back and is seen turning something off, but a few seconds later, his hand is again on the throttle, which is positioned halfway, as it used to be.
Correction: The captain is engaging reverse thrust. The throttle levers have two handles set at about 90° to each other. When the throttles are at idle, the reversing levers could easily be mistaken for the throttles at half thrust. This lever is then unlocked and pulled backwards to engage the reversers.
Corrected entry: Near the end of the movie when they are landing, Dean Martin is asked to help with the right rudder to turn the plane as it nears the end of the runway. In the Boeing 707 to turn the plane on the ground you use what is called a "tiller" that is left of the pilot. In the 707 the rudder pedals are not even connected to the nose wheel.
Correction: The plane has just landed significantly overweight and at a faster than usual speed. Captains Harris and Demerest are concerned about running right off the end of the runway. It's true that the tiller does the nosewheel steering, but the rudder will still be able to influence the plane's direction - they're using every available means to keep the plane on paved surfaces.
Corrected entry: Dean Martin requests a "PAR" approach to Lincoln. The controller confirms the requested "Precision Radar Approach" whose acronym is "PRA" not "PAR."
Correction: While the acronym is PAR since the term is technically "Precision Approach Radar", the term "precision radar approach" is commonly used, even in FAA documents I found in a Google search to describe the same thing, so having the controller use that term would be appropriate and understood by all the parties. Basically, one is the system (PAR), and one is the action (radar approach).
Corrected entry: When the bomber's wife calls in to the airline reservations office to warn the airline, the person taking the call uses a telephone handset, while the reservation agents sitting behind her are all using headsets.
Correction: How is this a film mistake? Some people don't use the headsets supplied with their telephone, some do.
Corrected entry: When Capt. Demerst tells Mel Bakerfield in the beginning of the movie that "when I'm setting down over 200 thousand pounds of 707 I want something under my wheels that's plently long & mighty dry", referring to the runway conditions, there's one problem. He's taking off, not landing. Wouldn't you assume that "setting down" would refer to landing?
Correction: It is mentioned that Capt. Demerest represents a group of airline pilots. His comment is likely made on behalf of pilots who will be landing at the airport under current conditions.
Correction: Captain Harris (the pilot flying) has his oxygen mask on. It's Cy Jordan, the flight engineer, who you see putting his mask on after the explosion.
