This is an airline that I almost forgot about. Can't remember seeing it at Luton that often either. This is one of the better photos of one of their Argosy's seen at Tempelhof. Didn't the Argosy have the same engines as the Viscount? I seem to remember that the aircraft used to scream like a Viscount.
