The first to PVR was Trenchard-he didn't get on with the minister-apparently. Nothing really changes!
Actually, my dear Lunchbox, Trenchard did resign as CAS before the post actualy became effective, he stayed on until about a week or so in from 1st April just to keep up appearances, just. He then went on to be head of the Indepenedent Air Force in France. Before returning 11 months later to become the longest serving CAS.
