A long, long time ago when my Attack Helicopter Troop was putting on a live fire demonstration for our Governor (some guy named Clinton if I remember correctly) and other dignitaries, one of our #1 gun pilots, clear of mind, so far beyond basic competence it was off the scale and probably 10,000 plus hours of stick time touched the wrong button and instead of firing 18 2.75 inch rockets, each containing 17 pounds of very high explosive were jettisoned and rolled across the ground about 75 feet below us going every way but the one intended, relieved of out load we went up like a runaway elevator nearly out of control....The outcome of this adventure resulted in an investigation by the Army Aviation Safety Office and you know what the outcome was....Oops! George said that he had just touched the wrong button, I saw him touch the wrong button, and our unit commander in the other seat told George at the time "You hit the wrong button" All the cause analysis, all of the investigation with charts, graphs and everything else resulted in what we knew from the start ...Oops you touched the wrong button. That's what I was getting at, the defects can be nothing more than....Oops and not a slam at people or anything else.
