What's still lost on me is why they couldn't still be called RAE and A&AEE
Clearly they
could still be called RAE and A2E2.
Why they are not (in my experience of observing organisations that go through some big change) is because the new bosses do not want to know about the past (even though it is what gave them their jobs) and try and suggest it all starts now chaps - hence we need a new name.
Sad really.
