On Maiden 1, the first American supersonic transport, Captain Jim Walsh, Robert Reed is at the controls for a bid to set a world speed record from New York to Paris. The flight crew includes Roy Nakamura, [Robert Ito], the flight engineer; stewardess Mae, [Tina Louise], and steward David, [Billy Crystal]. The ceremonial first flight brings together a mix of passengers and executives, all aware that this mission could redefine air travel.
On board are Willy Basset, [Burgess Meredith], the SST’s designer; Tim Vernon, [Bert Convy], the Cutlass Airlines’ head of publicity who is entangled with “Miss SST,” Angela Garland, [Misty Rowe], the glamorous public face of the aircraft; Hank Fairbanks, [Doug McClure], an ex-pilot turned aircraft buyer who hopes to rekindle a romance with Mae; and a host of other VIPs, including Paul Whitley, [Peter Graves], Bob Connors, [John de Lancie], Lyle Kingman, [Martin Milner], a former sportscaster, and his wife Nancy, [Susan Strasberg]. At the airport terminal, Harry Carter, [Regis Philbin], a television broadcaster and reporter, is there to cover the festivities. The tense mix of ambition, publicity, and prestige sets the stage for a high-stakes journey.
Trouble arrives when Les Phillips, [George Maharis], a disgruntled employee, sabotages the hydraulic system in an attempt to strike back at Basset. The sabotage triggers a massive inflight leak, and as the crew works to repair the damage, an explosive decompression ruptures a medical shipment of Senegal Flu, brought aboard by Dr. Ralph Therman, [Brock Peters]. With the virus on board, the SST is suddenly refused landing rights in Europe, turning a celebratory flight into a crisis. The pilots attempt a diversion to Senegal—the only country with experience handling the virus—but there isn’t enough fuel to reach a safe destination, forcing an emergency landing in a remote mountain pass.
In the aftermath, the spectacle of a luxury flight becoming a life-and-death ordeal unfolds. Some passengers are killed in the crash, while most survive, navigating the delicate balance between fear, endurance, and the will to press on. As the wreckage and weather close in, the crew and survivors face a daunting fight to preserve life, manage the outbreak, and find a path to safety, all while the clock continues to run. The story blends personal aspirations with the stark realities of danger, offering a stark look at leadership under pressure, human frailty, and the unpredictable chaos that can erupt aboard a flight meant to push the boundaries of speed and travel.
