Thank you... I remember an old episode of JAG where an operator on board a ship or sub was blamed for firing off a missile when he swore he had put a tag on the levers. It turned out that the tag had been knocked off (?) by someone and it was found under a cabinet when a missile had actually been sent on its way. Fiction I know but I believe some stories have authenticity.. And don’t disillusion me, please. I love the reruns at 9 ET each night.
Hence the need for the Lock as well as the Tag.
