There but for the grace of God go I. Live and learn, take sustenance from the sacrifice of others and let their lives be not in vain. Honour them by remembering the mistakes made and when you encounter similar circumstances, remember them. Add their experience to yours and so their memory will live on. It's the greatest honour you can give and the best thing is.........you profit too.
I know that area very well and have negotiated it many times over the last 33 years. I have a very vivid picture in my mind right now borne of my personal experience and that of imagination. I can [as others have alluded] postulate probable circumstance but would never dare to do so not at this time.
We all have been close to catastrophe at one point or another and more times than we might care to admit, as a consequence of our inadequacies. Please let us remember our own failings and with deference to camaraderie felt by all rotary wing addicts, desist from publicly making assertions especially when they are based upon conjecture.
Whilst I agree that there are lessons to learn from all incidents and that we all should take note, there is no definitive information yet, just supposition.
