Bibliographic research

[Antonio]

By manually searching through the patents in the Denver public library.

Wow!

Anyway (it is a personal feeling), Scott I think you are so lucky because you can research from original sources. I depend on books and magazines from others to discover unbuilt projects.

Your visit at Boeing archives was to be a pleasure

I think Vought has also an archive but when I sent an email looking for unbuilt projects info they told me they knew nothing about the subject
