As usual John, never a truer word said.
In my later stages ( late 80's- early 90's ) at BAe Dunsfold, none of us actually knew what the latest acronym we worked for was, we couldn't keep up.
I remember we were Military Aircraft Division for a while, until someone realised that spelt MAD !
A shame as you say, history and past achievements are buried by this sort of thing; and new bosses at any level who feel they ' have to be seen to make a change ' are just idiots grasping at straws.
