As Eric as pointed out, this is a world wide forum, not exclusively
USA. As a UK glider pilot, I'm interested in this subject, but have no
expertise to produce training videos myself.

It seems to me that much of this subject matter would be of
potentially common use throughout the world. I suspect that only a
minority of the relevant information would be country specific, such
as some aspects of air law.

I have seen some training material, for example on theory of flight
etc, produced by other people, but I do not have a library of it
myself. If there is interest in sharing a worldwide database, I could
put out an enquiry among UK pilots and clubs to see what might be
available for sharing.

Please let me know if anyone is interested.

What about Australia, Canada, New Zealand, South Africa, or anywhere
else?
