: C-47s of the 9th Air Force Troop Carrier Command tow reinforcements in CG-4 gliders across the Normandy beaches on June 6, 1944. The C-47s used a remarkable radar transponder system called Rebecca-Eureka to find drop zones, but weather delayed the pathfinders who carried the beacons, resulting in many gliders and paratroopers landing in the wrong locations.
