^^ I have absolutely no insights to offer and I know nothing on the subject. I posted it for information value for others. If I were an "interested party" I'm not sure I would "disregard all" given...
a. How complete and detailed is the account.
b. The CV of the author in aviation terms, which is frankly pretty impressive.
Given that the guy is willing to document and publicise it all, it would be a stretch to believe any of it is made up, would it not?
Are you saying his account is untruthful? Or is it matter of different types?
I totally bow to your knowledge and experience on type of course...but may I be impertinent enough to ask a question.
During your 4700 hours on type was normal practice for you and your students to wear a parachute?
Also this quote from your post....
Poor training, or lack of, and incompetence can cause death in any airframe.
....kind of opens up more questions in view of the nature of this specific tragic accident.
But not for me. I'll bow out. I don't wish to be accused of morbid curiosity and there are many others far better placed than me to have an informed discussion on this matter.
Thanks for your insights.
