GRAPEVINE, Texas (AP) - An American Airlines aircraft landed safely at Dallas-Fort Worth International Airport despite a dramatic discharge of flames from one of the engines. American spokesman Ross Feinstein (FYN'-steen) says none of the 139 passengers and crew was injured when Flight 438 to Seattle returned to Dallas about 20 minutes after takeoff Wednesday night. A Federal Aviation Administration statement says the pilot reported an engine problem causing compressor stalls, which discharged flames from the back of the engine. Feinstein says the left-side engine of the Airbus 321 was not on fire, despite the flames, and that the engine remained operational as the aircraft landed. Passengers are taking alternative flights to Seattle-Tacoma International Airport on Thursday.
