Invasion of Normandy
The American airborne landings in Normandy were the first American combat operations during Operation Overlord, the invasion of Normandy by the Western Allies on June 6, 1944, during World War II.
Here is authentic US Army Air Forces film # TF 1-3711 “Covers the invasion of Normandy when 13,000 combat troops landed behind German lines in 2 hours; & footage of both the 82nd & 101st Airborne units in action. Also included is official RAF Combat footage of Normandy battle from the Air.”
Goes into great detail about the glider and Troop Carrier plans for ferrying airborne troops and materiel. Sounds like Orson Welles narrating?
