The entire inlet and fan is missing from the GE /PW engine. FL370 over Greenland makes a "bird strike" unlikely. Bearing, stubpipe, blade failure(s) or a combination would be my guess.

Qantas A380 Trent engine failure explanation:

There are sensors for vibration, bearing lubrication, oil pressures thought the engine that monitor and track each parameter. All controlled through the FADEC system. So they should be able to come up with an answer. Even though the Qantas failure was on the ground and this one precludes the examination of missing parts.
