A large section of the fuselage of a Boeing 737 has been ripped off during flight. Excessive decompression was experienced by the passengers. Biologically, humans cannot breathe at 24,000 feet (less than 10,000 feet is the breathing altitude for humans). During the incident, the plane is still climbing to its assigned altitude so the passengers are still on their seat belts. The crew has still full control of the plane and made a successful emergency landing at Kahului Airport. Amazingly, only one died in this very rare air accident, a flight attendant (was sucked out of the plane) who was giving passengers drinks.
