That's about as massive of a structural/radical depressurization as you could expect, and the plane did not completely break apart in the air... in fact it landed safely, with only 1 casualty a stewardess who was not buckled in at the time of the failure.
United 811 had a major decompression as well, caused by a cargo door opening and busting through the fuselage.... it too did not break apart. Explosive decompression even massive ones like these don't seem to blow airplanes apart in air, even when flying at 500 MPH plus when the events occur. Other crashes blamed on structural failures that I can recall didn't break up in flight... I recall one where the real cargo door was repaired but only used 2 instead of 3 rows of rivets so the flex of pressurization/depressurization eventually lead to it just tearing apart in flight with massive decompression and loss of the airplane.
This plane is spread across 8 miles, it came apart in the air... meaning it broke up in the air, I have a hard time believing bad maintenance would have caused this to happen. I will happily sit back and accept someone with far more knowledge than myself on this, if they claim otherwise... an explosive decompression can certainly lead to the loss of an aircraft, but to completely break apart in air from a undetected stress fracture I would think would be unlikely.
Explosions are generally required for such things.. TWA 800, Lockerbie etc.
