Harry - you are fighting uphill here.
Eastern Airways was incorporated on 19th Nov 1997 and subsequently bought the AKL operating cert ( as a quick way to get started) in Feb 1999.
Thus your assertion that the moving of a SD-330 from Leeds to a flying club field in the late 80s was something to do with Eastern is wrong.
I know this because a) I worked for Air Kilroe b) I was a Leeds at the time c) I knew the two crew who "relocated" the Metropolitan SD-330 ... having taught one of them to fly.
Over to you.
