Boeing-777-Denver-Pratt & Whitney

A viral incident involving plane debris falling on a Denver suburb led Boeing to recommend grounding dozens of its 777 aircraft globally. United Airlines, the only US airline operating this model, removed its Boeing 777 planes powered by Pratt and Whitney 4000 series engines after an uncontained engine failure. The FAA has mandated more frequent inspections of these engines' unique hollow fan blades. Fortunately, no injuries occurred during the incident.
