Did C47's carry tanks in World War 2?

No, men only.

Not true; the C47 was used to carry supplies, including jeeps, which is why the military version of the DC-3 had double wide doors. I read an exciting story about a C47 used to carry a dissembled Steel Radio Tower. The tie-downs gave way, and the pilot fought for almost an hour getting out of the area which was surrounded by mountains. The C47's exploits in China tell of "flying the Hump" to drop supplies to Chaing Kai Shek's fighters. They were used to tow gliders for the invasion of Normany on D-day. I flew in a C47 from Honolulu to Midway back during the Korean War.
