USATODAY.com - Employees warned of heat on jets' entertainment systems

By Gary Stoller

A company that supplied entertainment systems for Swissair jets brushed off employees' concerns about the systems' safety, well before the product drew investigators' attention as a possible cause of a 1998 Swissair crash, two former employees say.

The employees say Interactive Flight Technologies' entertainment system produced excessive heat, which worried them. They contacted USA TODAY after it published an investigative report on the system on Feb. 17.
