Super F & Crab,
I think we all agree that excellent training is the most fundamental tool to avoid accidents, and part of that is CRM & TEM. We can't avoid risk in this environment, but if we can recognise the risks and take steps to mitigate them as far as possible, then we can go a long way to making missions safer (or less dangerous, depending on your standpoint!)
In this type of operation, where I imagine a degraded visual environment is common, you have to ask whether MP operations might go some way to mitigate risk. As far as technology is concerned, maybe a later generation of avionics with a safety/flyup function might provide a last ditch protection in some circumstances. Of course it won't work if you don't engage a collective mode, and of course it won't help if you fly into a cliff, but it might just have saved this helicopter.
There will always be the argument that technology gives you a false sense of security, and that pilots will rely on it when they shouldn't, but if you take that argument to extremes, it would suggest that we should all be flying around in unstabilised helicopters without FD, radalt, etc etc. In fact, if you are trained to use them appropriately, all these things can improve safety in particular environments.
