An off-duty airline employee flying as a passenger passed out while trying to help the flight attendant and suffered a cut above his eye.
The NTSB report notes that people can lose consciousness in as little as six seconds in the event of a rapid de-pressurization of an airplane cabin.
At the time, the incident raised questions about whether aging jets might be more susceptible to metal fatigue earlier than previously thought. But Hans Weber, an aviation technical expert, president of Tecop International in San Diego, told The Seattle Times that the NTSB analysis dispels that concern.
"The workmanship was just terrible," Weber said. "This has nothing to do with a typical fatigue fracture due to aging."
