On Saturday, 27 February 2021, a United Airlines 777 suffered a single-engine failure that resulted in engine shrapnel, including a near-intact engine cowling, falling on a Denver suburb below.

Just hours beforehand, a very similar incident occurred on a Boeing 747 in the Netherlands, which saw two minor injuries and cars littered with engine blade parts.

This week, the World of Aviation team investigated the two curious cases of aircraft engines suffering a failure, and raining shrapnel on the cities below them.

Host Adam Thorn and World of Aviation reporter Hannah Dowling walk through what we know so far about each incident, what we expect to uncover in the coming days and weeks, and the response of the parties involved.

    The Pratt and Whitney 4000 engine had not completed many flights or hours of operation and was not due for any scheduled inspections!
    Note: The engine installed in the Boeing 777-200 was a P & W 4000.

  • Rusty


    The engine family is “PW4000”. The engine model on that United B777 was a PW4077
