TorqueOfTheDevil "....:SARTU don't do change"
I was on SARTU in the 80s (not "rear-crew mafia, I hasten to add). I was at a Staff Meeting in which a change to some minor detail of "standard patter" was being discussed.
After a seemingly endless debate, a decision was finally taken, some wag suggested that the decision to bomb Hiroshima had probably been reached more easily. His observation went into the line book within minutes!
So I can confirm that SARTU do in fact do DO change - it just takes them a long time
