From Wikipedia
On February 20, 2021, United Airlines Flight 328, a scheduled domestic flight from Denver to Honolulu, suffered a contained engine failure shortly after takeoff from Denver International Airport (DEN). The aircraft, a Boeing 777 powered by Pratt & Whitney (P&W) model PW4077 turbofan engines, experienced a fan blade separation due to metal fatigue causing an engine fire and extensive damage to the nacelle. Despite being classified as a contained failure, as the fan blade fragments remained inside the nacelle, large parts of the engine's cowling, inlet and thrust reverser detached, creating a debris field over 1 mile (1.6 km) long across residential areas of Broomfield, Colorado.
The falling debris damaged private property, including the roof of a home and a parked vehicle. Witnesses captured footage of falling debris on smartphones and a dash cam, while passengers recorded video of the damaged engine and posted it to social media.
