There are roughly 300,000 flights that take off every day around the world. This number includes both private and commercial operations, and the majority of them take off and land without incident. In fact, the rate at which the thousands of flights are able to avoid any kind of crash makes air travel one of the most reliable forms of transportation on the planet. While traveling by air is generally considered safe, accidents do happen. National Geographic Channel’s (NGC) Air Crash Investigation S14 finds out what happens when a crash does occur. On February 24, 1989, United Airlines Flight 811 was making a routine eight-hour flight from Honolulu, Hawaii, to Auckland, New Zealand. Not long after the flight was in the air, passengers began to hear a disturbing noise coming from the floor beneath their feet. Suddenly, the cargo door flew off its hinges, causing the inside of the plane to lose air pressure. To save the aircraft and passengers, the pilots took emergency measures and managed to turn the plane around. Through the heroic efforts of the pilots that day, the plane returned safely back to Honolulu. Air Crash Investigation S14 goes into the details of what happened, eyewitness reports of what caused the accident, and how most of the passengers survived.
