With all due respect to those involved in the Mull of Kintyre incident, and I know there has been a LOT of comment on the flying sites, I think the comment "the apparent culture within the MoD of "don't confuse me with facts when I've made up my mind" that characterised the Mull of Kintyre Chinook crash investigation does not bode well."
I was an ATCO at Scottish Centre and my next door neighbour was the last guy to get a call from this chopper. IMHO and that of everyone I worked with during that period there could be no other explanation for the CFIT, given the Met conditions, than that found by the RAF Board of Enquiry.
As to the F15 CM that does seem very curious, although I do wonder whether they were given descent below the En-Route safety altitude without being informed of same? Although that said they were indeed responsible for their own terrain clearance.
