(Pasadena Star-News) Americans will forever remember D-Day — June 6, 1944 — as the largest air, land and sea mission of its time.

It was the beginning of the end for Nazi Germany at the cost of thousands of Allied lives. There would have been more bloodshed on the beaches of Normandy if not for the sacrifices of 1,000 glider pilots and co-pilots who risked their lives in engineless planes during Operation Overlord.

In fact, many people haven’t even heard of the CG-4A gliders, which were the stealth planes of World War II.

They were an essential part of the Allied invasion because they transported soldiers, jeeps, trailers loaded with combat equipment, and 75 mm howitzers and 37 mm anti-tank guns for paratroopers to use.
