I said in paragraph # 4 of my post that anything can happen.
I’m not familiar with the 1991 thrust reverser incident-did the pilot deploy it in error?
The 1989 incident-don’t recall it, but I don’t see how an “electrical short” can cause deployment of a door. There are interlocks built in those systems to prevent such a thing-not to mention mechanical locks. I’d have to know more about the specific incident before I could discuss it.
I do recall the Swissair OBE/electrical fire—Most OBE systems are not installed by the original manufacturer. I seem to recall that there were issues with the aircrew’s actions, materials, etc.—but this is all apples and oranges. The Flight 800 incident is different-the offical line is that wiring in the fuel tank was degraded to the point that it caused the problem. Some documents point specifically to fuel quantity system wiring—these capacitance type systems are measured in picofarads-one millionth of a miliionth of a farad.
I’ve heard of technicians putting a TF-20 Liquid Quantity Capacitance/Resistance test set on an aircraft and doing resistance checks, using the test set megohmmeter, on full/partially full tanks, finding shorted shielded cable-that check puts 500 VDC through the wire. Nothing happened.
I said in my original post that what the official line is improbable—but when you couple it with the non-technical big picture, lots of different big and small facts, plus eyewitness reports—hell, wasn’t July 19th Baathist Independence Day?—it seems kind of fishy.
Lauda Air Flight 004 on May 26, 1991. According to the black box and the flight recorder the flight crew did nothing. They just deployed.

United Airlines Flight 811, occured on February 24, 1989. Final cause was identified as improper wiring and deficiencies in the door design.

Why is that fishy and none of the other ones?
