Many of our passengers think that if the engines stop, the rotors start going round the other way. That is the sort of level of passenger knowledge the TSB might be up against.
HC, the TSB report will be factual, but as it will be made public IMO it wouldn't harm to have a "layman's" view and feedback included in the draft. Surely an eye witness PAX has an important input in such a review. Don't forget that it will be up to Robert to decide if he would wish to participate in such a review anyway, he's already shown great courage in being a key part of the inquiry to date. I'm assuming that Robert has not seen the draft report, so how could he possibly provide comment?
Oh, and I think you'll find that PAX are much more technically aware of helo operations these days, that tends to happen when you're made aware of the hazards and risks involved through real-life experiences.
Safe flying
