Chug,
Apologies, I know that you’ll have stated this clearly somewhere; why do you feel that the MAA and MilAiB do not function independently?
I ask as my previous experience of (actual participation in) service inquiries leaves me with the opinion that they are quite distinct and function independently (save for a rather trivial secretariat role) wrt inquiries.
I am aware of the governance structure hence asking about functional independence as opposed to ‘can or can’t be connected on a wiring diagram’.
