A United Airlines flight with 240 people on board developed an “engine issue” over a suburb of Boulder, Colo., on Saturday afternoon, shedding debris over three neighborhoods before landing safely in Denver, the authorities said.
There were no injuries reported, officials said.
Flight 328 took off from Denver International Airport at 12:15 p.m. local time and reported trouble with its engines, said Alex Renteria, an airport spokeswoman.
The police in Broomfield, Colo., which is about 15 miles southeast of Boulder, said unspecified pieces of the plane fell across three neighborhoods around 1:08 p.m. local time.
Rebecca Schulte, a resident, said she saw two pieces that fell just a few houses away from her home. She describe hearing a “mild sound” that she compared to an empty dump truck going over a pothole and then she heard sirens.
When she investigated further, she said, she found a “large metal ring” that landed on the front steps of a nearby home, striking the handrail.
“How it missed the house is beyond me,” she said. She said the metal ring was about 10 feet across.
A press representative for United did not immediately respond to a request for comment on Saturday afternoon.
Ms. Renteria said the flight was bound for Honolulu when the engine trouble occurred.
