I do remember the Fairford incident but had forgotten the details.
The GW1 incident came about because MOD insisted that a planned move from lbs to kgs for Hercules cargo went ahead. I phoned up the person responsible to get it delayed until after GW1 as the pressure on the movers etc was so great that there was bound to be an incident. His attitude was that this had been planned for years and it would go ahead. So we had our incident and at least one other 'near miss'.
