Part 1 of 2. Another 70^th anniversary D-Day special, this one runs two hours tonight and another two tomorrow. (Hey, look, Ma! The History Channel is showing some actual history!) And it, like many other new D-Day documentaries, is taking the time and opportunity to interview surviving veterans of that part of the war, who were as young as 18 at the time, and certainly are resources to be used now, and gratefully.
