To answer the question in Post 1
QUANGO!
This is a declared transfer of the old mentality into (presumably) a new building with an old Dept name on it.
The intent of H-C was to have a completely independant body consisting of non-military staff. This one is to be headed by a 3-star and is "already" populated by probably the same drongoes that caused the issue in the first place!
Given the size of the CAA in relation to the UK fleets of approx 1300 aircraft - this MAA has an assumed size of 250 before it even knows what it's going to do?
Smacks of a huge money-sucking QUANGO to me!
