This was very real to me, because my father took hundreds of photos from 1942 through 1945, of his time as a pilot in the CBI theater, and one of my four uncles who were stationed in England during 1943 and 1944 was a reconnaissance officer and flew with this group of Americans flying Spitfires. He later became commander of an RAF base.
Right now, I am trying to get my hands on the hundreds of photos my oldest uncle took as an infantry officer in France, 1917-1918, at Meuse Argonne, Chateau Thierry, Belleau Wood, and other major battles. His fellow officer, a friend from his home town who had enlisted with him, took a hand crank movie camera and filmed life in the trenches and the actual battles.
So this documentary excites me. It is very well done, and very personal, to all involved.
