My old boss, in another Gov department was on the Sheffield that day, and had left the Ops room seconds before the attack. Whether he is one of the two people cited in the article or not, I don't know.
He died some years later, from a particularly aggressive Cancer, from diagnosis to dead in a fortnight. His funeral was held in a large church, packed to the doors with people from the 4 corners of the globe, a well respected man.
