Hi!
I recently watched "BBC History of World War II: Hiroshima" (http://www.amazon.com/BBC-History-World-War-Hiroshima/dp/B000F4RH8Y/ref=sr_1...). I found this movie in local library.
Special features includes two documentaries:
1) "A Tale of Two Cities" made by US Army and Navy. 2) Interview with US Air Forces personnel participated in bombings. (However origin is not clear, so I'm not sure that this is PD). 3) Also some parts of main feature are just US Air Force documentaries.
I think will be great to have such documentaries in Commons (Commons doesn't seem to have it).
I'm not specialist in DVD ripping and Ogg conversion, so any help will be appreciated. I believe that experienced person could made this job much faster and better then me.
Eugene.
PS
However, I'm not sure that movie restoration is not creating new copyrights.
