A United Airlines flight with 331 people on board suffered an engine failure on Saturday afternoon in the suburbs of Boulder, Colorado, throwing debris in three neighborhoods before landing safely in Denver.
No injuries have been reported, officials said.
Flight 328 took off from Denver International Airport at 12:15 p.m. local time, said Alex Renteria, an airport spokeswoman.
The FAA said the aircraft, a Boeing 777-200, had a “right engine failure” shortly after takeoff and that there were reports of debris “near the aircraft’s flight path”.
The flight was being routed from Denver to Honolulu’s Daniel K. Inouye International Airport when the episode happened.
David Gonzalez, a United press representative, said the flight had 321 passengers and 10 crew on board. The flight was picked up by rescue workers as a precaution when it returned to Denver.
Police in Broomfield, Colorado, about 15 miles southeast of Boulder, said unspecified parts of the plane fell in three neighborhoods around 1:08 p.m. local time.
A video on Twitter showed a burning engine with parts of its case missing.
Rebecca Schulte, a resident, said she saw two pieces that were just a few doors away from her home. She describes how she heard a “low noise” that she compared to an empty dump truck going over a pothole, and then she heard sirens.
As she investigated further, she found a “large metal ring” that landed on the front stairs of a nearby house and hit the handrail.
“How it missed the house is a mystery to me,” she said. She said the metal ring was about 10 feet wide.
