Richard, once again you show your ignorance of security matters and the fact that at THAT time, all servicemen involved in the handling or coming into contact with such weapons, were subject to the Official Secrets Act. They were reminded of this regularly during their monthly security briefings. The following would have been the stock reply to ANY query regarding nuclear weapons!
1. Given that one ex Air crew when asked if there were any bombs in the RAF pre '62 replied Only iron ones.
Had this individual replied any differently, doubtless he would have been taken to task and been interviewed and reprimanded by his CO had the matter been made public. I have on many occasions in my time replied in a similar vein.
