Only saw a few minutes of "D-Day in HD" and wish I could see more. I knew several guys who were there. One of whom was my late dad; he was a 19 yr. old radioman aboard a light cruiser shelling German gun positions. From where they were in the channel he said that as far as they could see it was all the invasion force all the way to the horizon. One of his buddies who I knew ever since childhood was also a 19 yr. old radioman on a different ship a few miles away, although at the time they didn't know they were that close to each other. I grew up around WWII vets and all the ones I knew are gone now. I recently saw something that stated that only about 10% of them are still with us. We do owe them a tremendous debt of gratitude.
