For those who haven’t had the opportunity to follow this past weekend’s dramatic story, United Flight 328, a Boeing 777-200, departed Denver Airport bound for Honolulu at 1:04 p.m. local time. A few minutes into the trip, the airplane experienced what we call in the business a catastrophic engine failure. The event also qualified as an uncontained engine failure because various pieces of the engine scattered debris onto a nearby suburb. The covering of the engine, similar in function to the hood of a car and known as the cowling, completely separated from the engine.
