Eyes and ears...
Indications might be a.o. an abrupt near-0 indication of N1/N2, extremely high engine vibrations, enfine fire warning, strong fuel leak and stronger than normal yaw moment.

If it is an uncontained failure, possibilities include loss of hydraulics (Souix City DC10), cabin depressurisation due to puncture of cabin skin etc. If it is a sudden seizure, potential breakaway and loss of pod mounted engine (initially high yaw due to drag followed by recuced yaw after engine fallaway).

If you're interested, there was a paper produced by the FAA talking about the simulation of engine failure effects - I tried Googling for PSM+ICR but the FAA web link was broke :-(
However, searching the FAA web site I came up with this:
http://www.faa.gov/aircraft/air_cert...alf_report.doc
which, on first scan looks to have some further Good Stuff about engine failures and effects, particularly w.r.t. the training the group would like to see.
(PSM+ICR = Propulsion System Malfunctions + Inapropriate Crew Reponse)

To add to the list so far -
(1) Rotor speed (N1 / N2 / N3) at zero following failure (siezed),
(2) Zero Oil Pressure when the engine is windmilling following failure,
(3) Heavy vibration preceding and following the failure,
(4) Heavy impact sound just preceding failure (bird strike or FOD ingestion),
(5) Failure following excessive EGT (Turbine melt-down),
(6) Excessive duct temperatures associated with the failure (something has come adrift).
(7) Any fire indication, which may be false, but damage must be assumed.
The list goes on.............
