Missing something from AAIB report?
I've just read the AAIB report for the North Weald incident and I have to wonder if I'm missing something. The conclusion is that the planes collided because they didn't see each other, which seems reasonable. What seems strange to me is that no greater responsibility for this is placed on the pilot of the Yak than on that of the pilot of the Cessna. This seems strange in that it also clearly states that the Yak pilot turned left instead of right as expected by the definition of the run & break he declared he was doing.
Is the point that I'm missing the fact that see and avoid is always the responsibility of both pilots, no matter what procedures are or are not being followed?
Or is it that AAIB reports don't apportion blame?
