OK, something went wrong, first engine flamed out, second engine flamed out. That leaves plenty of time to enter autorotation. So why wasn't it done, (or if it was, why did the pilot flare much, much too early)?
Have the AAIB checked for pilot incapacitation, or included any kind of pathology or toxicology report on the pilot? And if not, then why not?
It seems to me that - after 109 pages - those are the main questions left.
