My apologies! I do recall now that you mention it that they were in fact DC-6s. No matter, these were great birds as well!
Sure are. Never saw the French 6s at all. Just a Turbo Tracker at an airshow in Lyon once. However I do remember sitting at the end of the runway at Fox Field in Lancaster, CA watching DC-6, P2V, and P-3 fire bombers take off. What a spectacle!
