Only one who seems close is old beefer,down in this hemisphere we have managed to scam the whole tape complete with Taiwanese commentary.More importantly the aircraft noise signature is clear throughout the incident.From this one can hear the aircraft arrive happily in the hover complete with its full quota of Nr.Very shortly thereafter there is a failure(probably engine but possibly Fcu)resulting in an audible Nr decay.From the initial failure the aircraft maintained a hover for six seconds prior to loss of tail rotor effectiveness.The rest should be fairly self explanatory.
A good advert for the dauphin if nothing else
