Poor Judgment Chain
aka error chain
Accidents and incidents rarely, if ever, are the result of a single cause
Usually a series of errors occurs which lead to the accident or incident
Break one link in the chain and sequence of events would be stopped

Communication
When the rear-seat pilot of a dual-piloted T-33 aircraft attempted to adjust his position, he inadvertently deployed the life raft in the seat bucket survival kit. As the raft inflated, it pushed the stick forward, which caused the aircraft to pitch nose down. The front seat pilot attempted to correct the dive, but met resistance when he pulled the stick back.

Communication, continued
Meanwhile, the back seater found and deployed the raft deflation tool. The front seater, trying to solve the control problem, heard an explosion as the cockpit filled with talcum powder from inside the raft, which looked very much like smoke. He identified the problem as an engine failure, closed the throttle and secured the engine.

Communication, continued
As the haze cleared in the back, the back seater noticed the apparent engine flameout and ejected. The front seater then dead-sticked the aircraft into a field. Throughout this entire sequence, not a word was spoken.

United Flight 232 Captain Al Haynes
– “We had 103 Years of flying experience in that cockpit . . . but not one minute of that 103 years had been spent operating an airplane the way we were trying to fly it. If we had not worked together, with everybody coming up with ideas and discussing what we should do next and how we were going to do it, I do not think we would have made it to Sioux City.”
