Goofs

Aircraft switching among DC-4s, DC-6s, possibly DC-7s.

When Tom and Marcia are having a drink in the lounge, close-ups show neither glass has ice in it. When Tom places his nearly empty glass on the table, there is the sound of ice cubes clinking in the glass.

During the flight, Walter opens the door in the lounge area of the plane and jumps out. Later, the question arises over whether the events occurred or were merely a dream. At the end, an official who was flying to Washington DC to investigate the missing flight is there, and the flight inexplicably arrives a full 24 hours late - demonstrating that the events were, in fact not a dream. But if that is the case, then Walter should NOT be on the plane when passengers begin to wake up.

Most DC4s not pressurized, flew with passengers below 9,000 feet. Captain requested 30,000 feet, barely beyond Service ceiling of DC-7, and this plane was apparently a DC-6, with a service ceiling of 21,000 to 25,000 feet. Most piston engine prop-liner flights were in the lower range of that.

When the emergency door is opened at 30,000 feet, a tremendous vacuum should suck everyone out the door. But since this is frozen in time, that may not happen.

The poster indicates that a jetliner disappears. The movie stresses that the plane is prop-driven and the pilot is looking forward to switching to a jet in a week.

The airline is supposed to be Trans-Coast. On boarding, the beginning of the "United" and on engine start at Los Angeles, the end of the "United" livery are clearly visible.

Marcia Paxton is in seat 6 and Dr. Morris in seat 10. When the flight attendant is walking the aisle just after takeoff, only two rows separate the two passengers where there should be four.

Near the end of the film, while the plane is on approach, the captain reads back a clearance and says "switching to ILS", referring to an "instrument landing system" approach. This is the second time he uses the term "ILS". Some viewers aver that here the captain says "YLS". This is caused by the vowel sounds of "to" and "ILS" being fused together. (Similarly, the phrase "eye-to-eye" can be heard as "I to why".)

Soon after the crew discover that the plane is climbing uncontrollably, there are two exterior close-up shots of the plane. In both shots, there are wisps of cloud swirling slowly around the cabin window. Before and after, there are views of the whole plane with clouds flying past at speed.

The story beneath the headline that the plane is overdue has nothing to do with planes. It seems to be about a judging service scandal.

At 4:45 the co-pilot fires up #3 engine and looks out the Right side window. The scene shifts to the outside where the inside Left engine is seen starting up.

About 10 minutes in, the flight attendant brings 3 cups of coffee for the flight crew. When she hands the 3rd cup to the navigator, she tips it. If the cup had been full of liquid it would have spilled.

After the establishing shot of the airport in the beginning of the movie, some crew and equipment silhouettes can be glimpsed at the bottom right corner of the screen.

While Dr. Morris, Marcia and Tom are sitting in the lounge of the plane to discuss their situation, a movie crewmember's shadow appears high on the wall between the Doctor and Marcia as they remove a shade panel from the scene lighting equipment.

When Tom and Marcia are walking around the inside plane after it has landed, a dark haired woman in the foreground, who is supposed to be unconscious, opens her eyes and looks around.

A couple is flying to DC, and the wife seems to be blind. When the stewardess brings her food, the husband leans over and takes her knife and fork, and proceeds to tell her what was on her tray and where it was. However, he was pointing to her food with the knife and saying "your potatoes are here", "your steak is there", and so forth. Hilarious, she couldn't see where he was pointing to.
