The Service Inquiry only states the servicing information, from 1991, could not be found. At the Inquest, this morphed into “Was not provided by Martin Baker”; yet no evidence was presented either way. I'd be surprised if the HSE and Martin Baker had not spotted this hole in the evidence trail. So, either this does not relate to the charge, or the hole has somehow been filled in. If the latter, why have we not heard of it, for example via a reconvened SI?
I say again, something is going on here. This case shares many similarities with the likes of Chinook, Nimrod, Hercules, etc. (systemic failings) but in those cases the HSE refused to get involved and MoD was permitted to judge its own case (and still is). This time the end game is very different. Now, MoD is (or should be) a witness in court of law, which it will find more difficult to influence. I can't imagine it is happy.
