Douglas C-53 Skytrooper, seen here at Hahnweide Germany.
The Douglas C-53 Skytrooper was a dedicated troop transporter developed from the DC-3 airliner. It was thus very similar to the C-47 Skytrain, but without the reinforced cargo floor, large cargo door and hoist attachment of that dual purpose aircraft. As a result the C-53 was much less flexible in operation than the C-47, and only 380 were built. Some sources quote 220 built.
