Cool. Glad you didn't add any muzak.
What camera did you use to allow nearly four hours of recording?!
You must have pissed-off a red-tail near your landing approach.
It would be cool if you could include a flight report in the vid description, including weather conditions, equipment, etc. etc.
Real-time commentary would also make it easier to remain glued to your video action. (I jumped around a lot) I've been using a voice recorder on my vids lately to good effect, and the spontaneous commentary as I'm flying makes them more fun to watch even for myself.
