One of eight medium-thrust engines fell off a U.S. Air Force B-52 heavy bomber from Minot AFB, North Dakota, in a Jan. 4 incident.

That was reported by www.military.com.

The incident occurred during a training flight near Minot Air Force Base, officials confirmed to Military.com. The engine broke up and debris landed in unpopulated area, they said. No injuries were reported.

“Earlier today, a B-52 dropped an engine while in flight,” a spokesperson said in an email. “The aircraft landed safely with no injuries.”

The five personnel on board the Cold War-era heavy bomber landed back at the base, another official said. Crews dispatched a UH-1N Huey helicopter to recover what was left of the engine, according to a base spokesman who spoke with Defense News.
