Airport '77 1977

Wealthy philanthropist Philip Stevens is in the process of inviting esteemed guests aboard his luxurious privately-owned Boeing 747-100, known as Stevens Flight 23, destined for his lavish estate in Palm Beach, Florida. Among the passengers are his estranged adult daughter and her young son, whom he longs to reconnect with, as he carries the heavy secret of being terminally ill. Accompanying them on this lavish flight are priceless artworks from Stevens’s exclusive collection, intended for his upcoming museum. However, this collection ignites the sinister interest of a group of thieves, led by co-pilot Bob Chambers, who plot to hijack the aircraft.

During the flight, Captain Don Gallagher is lured away from the cockpit and rendered unconscious by a sleeping gas that was secretly installed prior to takeoff. With the crew and unsuspecting passengers knocked out, Chambers seizes the opportunity to divert the plane towards a remote and deserted island to offload the stolen treasures, causing Stevens Flight 23 to disappear beneath the radar in the infamous Bermuda Triangle. As it descends to dangerously low altitudes, the aircraft enters a thick fog, reducing visibility to near zero. Moments later, a massive offshore drilling platform looms out of the mist, with the flight headed straight for it.

Chambers desperately tries to avoid a tragic collision, but in a fierce maneuver, a wing clips the tower of the platform, igniting an engine in the process. Despite extinguishing the flames, the aircraft experiences a critical loss of airspeed, placing it in imminent danger of stalling. As panic sets in, the passengers begin to regain consciousness, only to discover the terrifying reality of the unfolding disaster. With declining airspeed, the situation escalates, leading to a catastrophic stall that results in the plane plummeting into the sea, where it momentarily floats before submerging beneath the waves.

Resettling in relatively shallow waters above its crush depth, the fuselage begins to buckle under the mounting pressure. Many of the passengers suffer injuries, some gravely. Chambers, now the sole surviving hijacker, reveals that the flight is approximately two hundred miles off its intended course, misleading search and rescue efforts to the wrong location. As tensions rise, veteran aeronautics expert Joe Patroni joins the rescue operation as a technical consultant, alongside Stevens. Meanwhile, the trapped crew members can only signal for help by getting a buoy to the surface. Captain Gallagher and a fellow passenger, Martin Wallace, a professional diver, brave the main cargo hold in hopes of swimming to safety. Unfortunately, when the hatch door malfunctions, Wallace is tragically killed as water floods in, yet Gallagher manages to surface and activate the emergency beacon, alerting rescuers.

In response, the Navy dispatches the USS Cayuga along with multiple vessels to the scene, successfully rescuing Gallagher. Stevens arrives via helicopter while Patroni remains on land to assess the potential dangers of the aircraft imploding underwater, sharing urgent warnings with Gallagher over the phone. Under Gallagher’s supervision, Navy divers rig the fuselage with flotation balloons to hoist the aircraft back to the surface, although the operation is fraught with risk. Just as they near the surface, a balloon bursts, resulting in dangerously reduced pressure, threatening the structural integrity of the plane. A cargo hold door unexpectedly blows open, inundating the cabin, leading to the drowning of Chambers, who is trapped beneath a sofa, while Emily’s injured friend Dorothy succumbs to her injuries. The situation becomes increasingly dire as air pressure is manipulated, eventually leading to the plane’s ascent.

All survivors are rapidly evacuated, but Gallagher and Stevens’s assistant, Eve, find themselves trapped and must escape through the upper deck, where they are hoisted to safety by a Navy helicopter. Ultimately, with the loss of buoyancy, the 747 succumbs to the depths of the ocean one final time, disappearing beneath the waves. As the ordeal comes to a close, the survivors are taken aboard a nearby rescue vessel. In a poignant moment, Stevens reunites with his daughter, embracing his grandson with tears of relief. The helicopter transporting Gallagher and Eve lands on the Agerholm, where they receive heartfelt gratitude from the other survivors.
