A Southwest Airlines pilot discharged fire extinguishers in a cargo hold Thursday morning after getting a false fire warning as the plane approached Seattle-Tacoma International Airport.
Brandy King, a Southwest spokeswoman, said the problem was traced to a fire sensor failure in the forward cargo area of Flight 2981 carrying 126 passengers from Salt Lake City. She compared it to a false engine warning light in a car dashboard.
The light in the cockpit went out after the fire extinguishers were discharged, the plane landed normally, passengers disembarked as usual and an inspection showed no sign of smoke or a fire, King said. Firefighters met the plane as a precaution, she added.
