Valuejet Robert talks with Matthew Wald, a reporter for the New York Times, about the fire that brought down ValuJet Flight 592 last May. Airline safety experts are testifying this week at a hearing of the National Transportation Safety Board. Wald discusses what occurred at the hearing today, including speculation that the fire on board the plane may have started on the ground. The question of who should bear the responsibility for the accident has come into play in today's testimony; ValuJet, as the air carrier, or Sabretech, the company responsible for packing the oxygen generators now being blamed for starting the fire. There are some indications now that language difficulties among the Sabretech loading crew may have contributed to the confusion surrounding the loading and packaging of the generators.
