I hope you haven't forgotten the flight where an upper deck door was torn off in mid-flight due to wear & tear near Hawaii and it took a number of biz pax along on its journey to the bottom of the Pacific. Wasn't it a UA flight?</font>
Close, but no cigar. It was UA811, and it was the forward lower cargo door that opened due to a faulty latching mechanism:

United Airlines flight 811 experienced an explosive decompression as it was climbing between 22,000 and 23,000 feet after taking off from Honolulu, Hawaii, en route to Auckland and Sydney. The airplane made a successful emergency landing at Honolulu and the occupants evacuated the airplane. Examination of the airplane revealed that the forward lower cargo door had separated in-flight and had caused extensive damage to the fuselage and cabin structure adjacent to the door. Nine of the passengers were ejected from the airplane and lost at sea.
