D-Day remembered by World War II air cadet in letter home

Seventy years ago today, June 6, 1944, the largest seaborne invasion in history took place: D-Day. About 6:30 a.m., 24,000 British, US, and Canadian airborne troops landed on the beaches of Normandy. Thousands of young men lost their lives there, and their sacrifice eventually helped the Allies win the war.
