Leon, good point, and I'm not sure what is meant by the AAIB "convening a five member Board of Inquiry". The BoI would surely have been convened by the AOC (38 Gp?), and as was made clear by SoS Healey was not to be held in public. I can only assume that the AAIB took a lead role in the Inquiry and so was free to use its expertise to swiftly find the cause and have its recommendations constitute much of the BoI's findings. A rather more proactive state of affairs than occurred in the Mull BoI whereby the AAIB Inspector was greatly constrained in his role. Hopefully we can source the BoI Report and all will be made clear...
