I have plenty of happy hours in SKJ & SKW when they were Skytrans; BUY was originally Vic Polair IIRC, then bought by Qld Ambulance for the Bundy base (ergo 'BUY'), went to RFDSQLD as a spare when they took over the air ambulance gig before being sold to a Darwin operator. These were 3 of the nicest, best equipped 404s in Aus, sad to see them ending up like this.
