A Southern Air Boeing 747-200 suffered the loss of all four engine-driven electrical generators while en route from Miami to Anchorage, Alaska, on September 12. The Boeing landed on Anchorage’s Runway 7 Left using the aircraft’s two emergency generators.

Because the aircraft was operating on emergency power, the jumbo’s anti-skid was inoperative, which caused 14 of 18 tires to blow out during rollout. The NTSB is investigating the incident.
