Looking for AUDIO clips relating to WWI pilots for a CD-Rom

I'm currently working on an educational multi-media interactive CD-Rom on World War One Air Combat. I'm having a difficult time tracking down audio clips from the time period, or any time period pertaining to the pilots who flew in the great war. If anyone is able to offer assistance it would be greatly appreciated.

I should point out that this project is for a College course and will be non-for-profit... just for-grade =)

Here's a link to a page with the audio of an eye-witness account of the downing of Richthofen: http://www.anzacs.net/MvR-Eye-Witness.htm You would likely to need to get permission to use these audio excerpts, however. Jack

I meant for it to show up as an actual link, like this:
