While I agree with most of Beagle's comments about the dear old Vulcan, I think a possible slight on the Spilsby crew may have occurred. As I recollect the Board's initial report was all set to pillory the crew, and AEO in particular, after the crash, but after the digging and reconstruction they had to back off. The RAT in question was seriously over-volting. and arcing from poor insulation onto a previously pitted fuel pipe started a fire which was unstoppable. I seem to remember that in effect pulling the handle to deploy the RAT in this case started a chain of events which the crew could in no way prevent.
I only remember one instance of the RAT literally dropping off. I do recall a few which did not work as advertised, albeit rarely
