Thanks Brian for the C-54A Skymaster remainder. Strange decisicion send them direct, as long before (from spring 1943) them westbound ATC C-54 flights had already routed thrugh Meeks Field (Keflavik), only adding about 4-6 hours to the trip. In winter 1944/1945 these Meeks fuel-stops were NOT suspended for the winter (as had been in winter 1943/1944, but by February they begain trickle again thugh and from March they were regular visitors.)
As side note (Record) History ATC North Atlantic Wing, is available but I have not looked at those films for years. This particularar plane C-54A was AAC 41-37281 assigned/operated (by) American Airlines (AAL), as were 18 other Skymasters in summer 1944. List of all these as of 6 May 1944 is attached.
