The FAA funded a study of actual in-service events in the 90's to statistically evaluate the forward and aft trajectories of uncontained rotor engine parts. The greatest spread was seen to be fan blade particles with the outer panels often going forward into the soft inlet cowling and the innermost panels of blades going aftward if they did manage to escape through the engine casing.
However, it's not clear at this time whether the reported aircraft damage was caused by engine blade particles or release of aircraft cowling particles.
In this latest incident the degree of visible damage to the engine core cowls seem to be much greater than the earlier event pictured earlier in this thread.
