The MG escaped and then returned.
Sounds like another meddling senior officer decision subsequently overturned....
No doubt the Cat scheme has been re-invented as well?
When I was an IRE, I looked for smoothness and overall management as the decider between G and MG. If the candidate flew to the limits that was one thing, but to do it and make it look so effortless was quite another.
That said though, I really don't see the point in 2 levels of qualification which have identical privileges.
