Jonathan,
Your video expertise is far beyond my knowledge of the subject, but I will offer a few comments.
1) A narration rather than noisy sound effects would have made your video... better? The music selection will get old, but a narration will endure and offer insight to someone willing to invest their time to watch and study. While the quality of your video is impressive, don't quit your day job just yet.
2) You can edit your articles. It would be appreciated that if you choose to promote an older article to the top of the list that you take the time to review your links. Your initial posting has numerous links that no longer resolve. It's not realistic to expect others to ponder your essay if you don't proof it yourself.
3) Ground school 101. The wind velocity has no effect on the closing speed of 2 gliders approaching head on. Based on my reading of the articles, it find it highly unlikely that your closing speed was 80 to 90 mph.

I didn't fly in 2009 and missed the postings at the time. It was a fun read.
Thank you for your contributions
