After man opens plane door mid-flight, flyers ask: How can that happen?

After a passenger opened the emergency exit door during the approach, the Asiana Airlines A321 touched down without incident at Daegu Airport in South Korea. Nine people were sent to the hospital due to breathing problems.

A guy who reportedly opened an emergency exit door while the aircraft was still in the air and prepared to land. could face 10 years in prison. On Friday, fliers about the incident asked: How could that happen?

Opening an aircraft door is impossible while the plane is at cruising altitude or above 10,000 feet due to air pressure. Modern commercial aircraft are designed and built with airtight cabin pressurization systems. These systems ensure that the cabin remains pressurized at a level that allows passengers and crew to breathe comfortably. The difference in air pressure between the cabin and the outside environment creates a force that effectively seals the doors shut.

However, as the plane descends, experts think it is conceivable for a door to open when the pressure inside and outside the plane equalizes. The pressure within the cabin is high enough at cruising altitude to push the door of the aircraft up against the hull, but as the aircraft descends, the pressure starts to equalise. It is feasible for that door to be opened while the aircraft is still in flight at very low altitudes.

Everyone should to have been wearing seatbelts considering that this incident occurred at a very low altitude right before touchdown. However, the guy who opened the door was undoubtedly at risk of falling out of the aircraft.
