Talk about an old film! It’s from 1917, and it’s an up-close and personal look at the most legendary combat pilot who ever lived, the infamous Red Baron, Manfred von Richthofen. It shows the Baron preparing for a mission, as well as film of him putting on a flying suit prior to a flight in cold weather. (It is always cold at higher altitudes.) If you look closely you will also see a brief glimpse of Hermann Goering.
The Baron was shot down on 21 April 1918 by Roy Brown of the Royal Navy Air Services, long before it was called the R.A.F.
