.... after viewing "Wunder des Fliegens" I came across a link to this,
YouTube - Broadcast Yourself.
A program from a documentary series "Hitler's Warriors". This particular episode is "Udet the Flyer" which is both interesting and odd. Udet's Great War service is given sparse treatment. A film and photograph of Boelcke are misidentified on two seperate occasions as Manfred von Richtohofen and then Udet. On the latter occasion Udet is then condemned as vain for having a photo of "himself" displaying the Pour le Merite!
A bit too much of a rush to condemn.
Note also the link to "Building an Albatross D.III".
