No, Caco, not setting a trap for you. Yes I read the interim report and I cannot deduce from that that the pilot attempted to turn the machine to the left, and the Sun video does not show any yaw to the left (as far as I can see) before a rapid yaw right, which appears to follow a very small right turn. At that point I propose the pilot would have been rapidly applying significant left pedal! Hence the query on the FDR which I guess all assume shows a left pedal before the failure? I had surmised the tail rotor ran fully 'right' at the point he yawed right. However, the AAIB will know. As they say "The cause of the apparent loss of yaw control has yet to be determined."
Regarding the 'second pilot', I recall my days flogging round Scotland in an 'Air Taxi' with Loganair flogging around with their 'second crew member' - the 'Radio Operator' in the right seat - often a PPL trainee or similar!
