UKpaxman, no not really. I am presuming you mean some sort of ballistic recovery system as fitted to some light aircraft. The trouble with many of these ideas (apart from cost and weight) is the risk of inadvertent deployment. Parachutes and rotor blades don't mix well together!
Despite these accidents, and lets remember that only 1 was a catastrophic failure (because I don't think the injury pattern of this latest event points to catastrophic failure) in all the Super Puma operations since 1982 (on UK side). A ballistic recovery system would have to be incredibly reliable to suffer less than 1 inadvertent deployment in that time. Also you would of course have to stop or jettison the rotors before deployment. Scary!
