Passengers Exposed at 17,000 Feet: The 20-Minute Nightmare of Flight 5390

Commercial airliners fly higher than Mount Everest in an environment that would kill a human instantly. To keep us alive, every plane is a pressurized life-support system—but what happens when that pressure escapes? In this aviation documentary, we break down the terrifying history of explosive decompression and the fatal design flaws that changed aviation forever. From the tragic metal fatigue of the De Havilland Comet to the miracle landing of Aloha Airlines 243, the near-fatal windshield blowout of British Airways 5390, and the ghost flight of Helios 522, discover how the safety regulations of modern aircraft were quite literally written in blood.
