Uncontained turbine blade separation

Not sure there's much to "press" about. Engine failed. Pilots landed.
 
System worked as designed. Failure was contained, flight controls were unaffected, and the aircraft landed safely.
 
Not turbine blade failure. Uncontained fan failure. Rare. Wonder if the engine stalled prior to the fan failure? Interesting. The only fan failures I've see were caused by ice ingestion or the two L1011 engines that had the fan shaft fail and the fans walked out of the engine. Tom?

Not really that rare. Can be caused by FOD or by undetected fatigue cracks in the blades.

Not to pick on DC-10s, but the famous no control DC-10 at Sioux City was caused by an uncontained failure of the center engine, they eventually found most of the fan in a cornfield.

There was another incident with a DC-10 years ago where there was an uncontained failure of one of the wing engines, one of the fan blades took out a window and the passenger seated next to it was ejected, see: http://www.ntsb.gov/ntsb/brief.asp?ev_id=85098&key=0&print=1

Jay, the incedent you reference was a turbine wheel which had cracked and failed. This appears to be a compressor fan failure which is rare due to them not being exposed to the stresses that come with heat from the combustion section of an engine.
