I think that the politicians will overrule the MOD in the end, incorrectly in my view, but on the grounds that there could have been some remote possibility of a technical failure which prevented the pilots from extracting themselves from a dangerous situation that they had placed themselves in in the first place. The likelyhood of that really having being the case, in my view, would be in the region of about a .01% probability. However, as his Tonyness is a master fo 'spin' I think that he will probably use that line of reasoning to pacify what he believes is the 'public view'in the case.
My own feeling is that the MOD should stick with their decision.
