To me, this movie is perfection.

Absolutely amazing

Watch something else. There are very few redeeming qualities to this film.

Story: It's very simple but honestly that is fine.

Rod Serling, famous for "Twilight Zone," was one of the most gifted screenwriters in Hollywood. In addition to his two television series (the other the vastly underrated "Night Gallery"), he wrote the screenplays for classics such as "Seven Days in May" and "Planet of the Apes." His talent is undeniable and Serling deservedly is a legend."The Doomsday Flight" has the trademark Serling creepiness. Edmond O'Brien, another tremendously underrated Hollywood talent, carries the film with an eccentric but oddly winning performance of a man living on the edge. The cast is loaded with familiar faces such as Edward Asner, John Saxon, and Jack Lord, but O'Brien provides the tension this kind of film badly needs.Serling was something of an authority on airplanes. His older brother, Robert, was an esteemed aviation writer, and Serling himself was a paratrooper during World War II. So, he knew a lot about the aviation industry and the gaps in its security.The plot here is simple. A man places a bomb on a passenger plane (a fictional Boeing 797). It is set to activate when the plane ascends to a certain height, then detonate when it descends below that altitude. The plot is thus somewhat similar to that of Sandra Bullock's "Speed."The performances are gripping, especially for a television movie. Van Johnson as the pilot and Lord as a troubled FBI agent. The direction by William Graham is outstanding for a film of this type, and overall it is a quality production.There's a fatal problem with the script, however. Serling obviously knew all about pressure-sensitive detonators. They were developed during World War II for military applications. Such detonators do, as the script points out, detonate on air pressure changes at specific altitudes. So, when a plane reaches a certain altitude, they do intend blow up. The "arm after reaching the altitude and then detonate on the way down" is a minor complication.The problem with the script is that the pressure doesn't change in modern passenger aircraft. The cabins are pressurized. In fact, the cargo holds are pressurized, too. Pressure-activated detonators may work on World War II aircraft that weren't pressurized, but they wouldn't work on a "Boring 797" because the pressure inside the aircraft doesn't reflect the outside air pressure. Even if the cargo hold were not pressurized, there would be no way for the airplane crew to disarm the bomb because access to the cargo hold from the main cabin is impossible - so a ransom threat wouldn't work. Serling undoubtedly knew all that, but figured the audience wouldn't - and, undoubtedly, he was correct.Anyway, a well-made production that undoubtedly influenced the later "Airport" which began the entire "disaster film" craze of the 1970s (and there are some nice explosions in this film). Worth a watch, just try not to think too much about it.

Back in 1966, "The Doomsday Flight" wasn't quite as familiar and tired a genre film as it would seem today. The "Airport" films were all made a few years later, though a few air disaster flicks had preceded it as well, such as "The High and the Mighty" and "Zero Hour!" in the 1950s. This take on the air disaster films is a bit different because it was made for television and it was written by Rod Sering. The overall effort is about as good as the better air disaster pics...and a lot better than the really bad ones (like "Airport 75").A cross country flight has many of the usual caricatures aboard. A maniac (Edmund O'Brien) calls the airport to tell them that he's put a bomb aboard the plane after it's taken off. He informs them that the bomb will automatically activate itself when the plane drops below 4000 feet! There is then a mad scramble to try to find out where the bomb is and provide the creep his ransom money if they cannot find and disarm it. The agent in charge of all this is played by Jack Lord but Gregg Morris and Ed Asner are also on hand to handle the case.The best thing about this film is probably the maniac. Edmund O'Brien is very malevolent and seems to delight on toying with everyone. It also becomes apparent that even if they pay him, he might just let the plane explode anyway!! A very tense and well made film with many aspects which were used in the parody film, "Airplane II". Worth seeing but familiar.

WARNING!!! MAY CONTAIN SPOILERS!!!This is a pretty decent thriller from the mind of Rod Serling. However, the ending looked as though it were thrown together at the last second. The idea of a bomb going off at a certain altitude was fine, but the fact that at the climax of the film a light went finally came on when he finally realized that he could land safely in Denver, which is well above the point where the bomb was set to explode. A three year old could figure the ending out. But despite this, this is still a great thriller. Rod Serling was one of the greatest writers in television and film history and this film only confirms this.

Think Rod Serling wasn't a Thunderbirds fan? Then check out this 1966 telemovie about an airplane with an altitude-sensitive bomb on board, programmed to explode upon descent - the plot is a direct inspiration from Thunderbirds' pilot episode "Trapped In The Sky."
