The remarkable thing is that 4 exocets hit their targets, caused considerable damage, but none of them exploded! The worst damage was caused when the flame from the solid fuel rockets of the exocets ignited the aluminum hulls, which then could not be extinguished. The british have since reconsidered their decision to build their ships out of inflammable metals. Aluminum will burn even under water, and the only way to extinguish the fire is to smother it with inert materials (non-oxygen bearing).

At the time I thought that one failure to explode was possibly accidental equipment failure, but for all four to fail, that had to be a kill switch. I think the british had the kill codes for the exocets, but only used them to disable the explosive, not the targeting, not thinking about how the heat of the fuel would set the aluminum hull on fire. They were probably under some obligation to the french not to reveal the existance of the kill codes, and to not use the kill codes so as to make the exocets look really bad, like turning them around and hitting argentine positions. that would really kill the market for exocets, wouldn't it.

The wikipedia article on exocets documents the falklands/malvinas war, noting that none of the exocets to hit their targets, actually exploded ... here's wikipedia on the three british ships struck by exocets:

"On 25 May 1982 the Atlantic Conveyor was hit by two[2] Exocet missiles fired by a pair of Argentine Super Étendard jet fighter. The ship caught fire, the fire then became uncontrollable. When the fire had burnt out, the ship was boarded but nothing was recoverable and so the decision was made to sink her. It is unclear whether the missile's warhead detonated ..."

"The Exocet that struck the Glamorgan failed to explode, but the unburnt rocket fuel caused a significant fire."

"The crew of the Sheffield and members of the British Task Force were of the opinion that the missile had exploded, but the official report from the RN Board of Inquiry, now available (2007) on the Internet, states that from the evidence available the warhead did not explode. The damage caused was due to the large kinetic energy of the missile, and the unused missile fuel that ignited on impact."

imagine what the damage would have been if they had actually exploded!

the cleaners have physical access to your everything. what contract did you sign with them? you know, to minimize your risk, you should outsource your IT to the cleaners. they already have physical access to everything, so it's not much of an extra step to let them maintain your systems too. they're even in the office on a daily basis. if you have any IT issues, just leave them a note!
