More than 500 U.S., French, Dutch, Romanian and German paratroopers jumped out of nine U.S., French, Dutch and German C-130s and C-160s near here June 3 to pay tribute to D-Day veterans who demonstrated the selfless service and sacrifice characteristic of the Greatest Generation. This year marks the 74th anniversary of Operation Overlord, the Allied invasion of Normandy on June 6, 1944 -- most commonly known as D-Day. An epic multinational amphibious and airborne operation, D-Day forged partnerships and reinforced transatlantic bonds that remain strong today. Overall, U.S. service members from 20 units in Europe and the U.S. will participate in events and ceremonies May 30-June 7, in almost 40 locations throughout the Normandy region of France as part of Joint Task Force Normandy 74.
