Swissair Shuts Jet Entertainment Units

Swissair has voluntarily shut down the high-tech entertainment systems in the luxury cabins of its Boeing 747 and MD-11 jetliners after a Canadian probe of the Sept. 2 crash of one of its planes found heat-damaged wires connecting the system, the company said Thursday.

Investigators have been looking into the possibility that faulty wiring resulting in a massive electrical failure may have caused Swissair Flight 111 to plunge into the Atlantic Ocean off Nova Scotia, killing all 229 people aboard. Minutes before the crash, the pilot reported smoke in the cockpit.

U.S. officials said preliminary checks showed no U.S. airline used that type of entertainment system.
