airflow kept the rotating group spinning
there really isn't a way to stop it with out jabbing a 4X4 in the front of the engine
usually/frequently loosing a fan blade will jam up the works enough, but not in this case
And the rotation speed seemed to be close to a vibration mode of the aircraft, so the bad effects were really pronounced
The granting of a pardon is an imputation of guilt, and the acceptance a confession of it.
