"Oh, you pilots are such men." "They don't call it the cockpit for nothing, honey." Dialogue like that is just one of many reasons why The Concorde… Airport '79 (or, if you saw it in the UK where it dragged its heels getting released there, Airport '80: The Concorde) was the last and by far the least of the series. The disaster movie was in dire straits in the late70s, what with The Swarm having offered much unintentional hilarity and Beyond the Poseidon Adventure, When Time Ran Out and City on Fire simply offering much boredom, and the desperation to find a new spin on the genre is all too apparent here. This time it's a conspiracy plot, with Susan Blakely's news anchorwoman discovering billionaire boyfriend Robert Wagner has been selling arms to terrorists and the North Vietnamese. Naturally, she decides to tell him everything rather than make the story public, but, he fobs her off by explaining "I'm a very rich man. I have everything in life I could ever want. Why would I jeopardise that by doing something so incredibly stupid?" Just in case she doesn't buy that line, rather than, say hire a hit-man to kill her on the ground, he decides to do things the smart way by planning to destroy the Concorde while she's flying to Moscow via Paris. "I've done a lot of things I've been ashamed of, but I am not a murderer," he insists indignantly on his way to reprogramme a guided missile to destroy the plane. So, nothing incredibly stupid there. And when that fails, he sends a jet fighter after it. And when that fails…

Don't even think of looking for anything resembling logic here: this is real bottom-of-the-barrel stuff that even the studio gave up on and marketed as a comedy in the US after critics laughed it off the screen. Where the previous three entries all had the look of glossy big-budget entertainments, this small-screen friendly effort (the only one not to be shot in 2.35:1 widescreen) doesn't even manage to make the Concorde look good, which is quite a feat. TV veteran David Lowell Rich presumably got the directing gig because he was fast, cheap and had previously directed TV movie SST: Disaster in the Sky where Peter Graves' supersonic airplane found itself unable to land due to sabotage and Senegalese flu (which was not, intentionally at least, a comedy despite the presence of a young Billy Crystal in the cast) and seemed like the natural choice for what looks like a $14m TV movie that somehow escaped into theatres when no-one was looking.

Cast like a bad episode of Hollywood Squares, stars are in very short supply this time round, and most of the few vaguely familiar faces seem to have been rounded up from rehab clinics and busted sitcoms. Alain Delon gives the Hollywood career that one last shot as the pilot, "Happy Fish" (don't ask) George Kennedy moves from the executive suite to the co-pilot's seat in the hope of reminding people of the other movies, while the rest of the ensemble includes a couple of veterans of The Towering Inferno (Wagner and Blakely), a soft-porn star (Sylvia Kristel, trying to go respectable), an Ingmar Bergman regular (Bibi Andersson – and she's the one playing the hooker!), David Warner's navigator on a diet having nightmares about being chased by bananas, the voice of the Devil (Mercedes McCambridge), Charo and her Seeing Eye Chihuahua ("Dohn miscon-screw me"), Martha Raye and her weak bladder, Jimmie Walker playing the sax in his seat and smoking weed in the john (in the few moments its not occupied by Martha Raye), Cicely Tyson kissing her credibility goodbye as the obligatory mother with critically ill child and a frozen heart in the overhead locker, airline owner Eddie Albert and trophy wife Sybil Danning occupying the best seat in the house, Ed Begley Jr in goggles, and the Russian Olympic team and their lovable coach Val Avery and his deaf daughter (ahhhh!) on a goodwill tour of the States (who knew about the boycott?). Just to add a touch of The Simpsons to proceedings, Harry Shearer voices one news report in the same tones he'd later use for Smithers.

Highlight? Despite the impromptu wedding ceremony during a crash landing, it just has to be George Kennedy diverting a heat-seeking missile by opening the window, sticking his arm out (at nearly twice the speed of sound!) and firing a flare – while the plane is upside down! And then Alain Delon turns off the engines so there won't be a "heat source" for the missiles to home in on… Yes, someone actually got paid for writing this, and that someone was future Oscar winner and screenwriter of Munich and The Insider Eric Roth (hey, everybody has to start somewhere), although in his defence it was producer Jennings Lang who came up with the plot. Still, what do you expect from a film that credits stunt balloonists and ends with a shot of the Concorde flying off into the sunset? Amazingly, in one of those won't admit defeat moments studios used to be prone to, Universal shot another 20 minutes or so of footage a couple of years later to include in the network TV showings (not included on the DVD). Sadly its box-office failure led to the fifth entry in the series, the laugh-riot that would have been Airport 1984: UFO, never getting off the ground. Even more genuinely tragically, it was the Concorde used in this film that crashed in France 21 years later.

(Oh, and if you're wondering what Charo says to her Chihuahua in unsubtitled Spanish when it's not allowed on board, it's "What do you think? Don't worry. When the revolution comes, I promise you will fly on anything you want. I promise. What a shame, my love. What do they think they are?")
