Although not operating entirely without incident.
Longtail Aviation flight LGT5504, a Boeing 747-412 (BCF), suffered an uncontained engine failure of the no.1 PW4056 engine. Blade fragments were ejected from the engine, coming down in the village of Meerssen, 2 km past the end of the runway. At that point the aircraft was climbing through 1400 feet.
