The Federal Aviation Administration said a United Airlines plane bound for Honolulu suffered a right-hand engine failure on Saturday shortly after it left Denver International Airport, scattering debris but returning safely to the airport.
United said in a statement that there were no reports of injuries on board Flight 328, which had 231 passengers and 10 crew members on board.
Bromfield, Colorado, police released photos of parts of the wreckage of the Boeing 777-200, but there were no immediate reports of any casualties on the ground. The Federal Aviation Administration (FAA) said it will investigate with the National Transportation Safety Board (NTSB).
Pictures released by the police department appeared to show large chunks of debris, including the engine cover of the plane, strewn outside a house and on the grass.
A video clip on social media showed a cloud of black smoke left by an aircraft.
In the video, a man can be heard saying “Something has exploded”.
“If you find a wreck, please don’t touch or move it.” The Broomfield Police Department said on Twitter, “The NTSB wants all debris to remain in place for investigation.”
