The incident you refer to involved 8 x 8 mx loads (4 Skyflash, 4 AIM9L) during Op CORPORATE, Leuchars to ASI. All motors and warheads armed, and fuse covers and noddy caps removed by the LM. ISTR the AIM9L were returned to the UK because of suspected damage to the seeker heads - the noddy caps were there for impact protection but also to prevent the un-powered heads bouncing off the stops. CM will probably be able to spout the technical details for you because he was a QWI and had to learn all that stuff.
