I have never seen the relevant documents, and I therefore do not know. Regards JP
What relevant documents, JP? On this thread alone there has been an abundance of links published, including ones to the HoL hearing to which dalek refers. Just as with your "unfamiliarity" with airworthiness the abiding impression is one of a disingenuous attitude in your posts.
Never mind documents JP, seen or unseen. What possible justification was there in the BoI failing to call the one man, both experienced and qualified with the flight and engine control shortcomings of the Chinook HC2, to give evidence to them? Why was Sqn Ldr Burke forbidden to contact them if it wasn't to hide such shortcomings?
