Bell’s new helicopter may look but it could reduce accidents and noise

Silly question, but I wonder if manufacturers have done R&D for some kind of, er... emergency anti-twisting baffle?

I'm imagining something vaguely like a giant air mattress that inflates out the back/bottom when the tail rotor fails, a supplementary vertical fin.

I suppose that the benefit might not be that big If all that does is change the fuselage spinning from "extreme" to "severe." Above a certain rate helicopter is still going to go down.

What I find strange (?) is that the LAA does not seem to be run by the government, but by a charity:

> London's Air Ambulance Charity is a registered charity that operates a helicopter emergency medical service (HEMS) dedicated to responding to serious trauma emergencies in and around London.[3] Using a helicopter from 08:00 to sunset and rapid response vehicles by night, the service performs advanced medical interventions at the scene of the incident in life-threatening, time-critical situations.
