On the trip the guys made to see the Martin Mars fly, we stopped by Victoria International Airport on Vancouver Island.  Round the back of the field, there were two S-61 airframes sitting doing nothing in particular.  One was in the markings of British International Helicopters.  It has been a very long time since I last heard of that operation.  Apparently, the company has gone through various incarnations over the years.  It did operate scheduled flights to the Scilly Isles off Cornwall with S-61s so maybe this airframe came from that service.  Has it been sitting here ever since?
