It never ceases to amaze me that after all this time people keep plugging into this thread and throwing in ideas, concepts, theories, possibilities, probabilities, hypotheses, simulations etc, etc.
Of course everyone is entitled to their opinion on what happened, whether they are an "expert" or not. However, what this whole campaign can be boiled down to is the "unwarrantable arrogance" of two airships, which condemns two men who cannot defend themselves.
Think abou it, there are only two men on this planet who "know" exactly what happened in the last minutes/seconds of that fateful flight. I said this recently to someone who has very close connections with the old RAF Inspectorate of Flight Safety. The response was "that's a cynical statement".
No it is not! To have "absolutely no doubt whatsoever" Day and Wratten must "know" exactly what ocurred. How can they? Arrogance? Too bloody true!
