I just thought reading the prelude we'd get the whole picture in your movie... But no. If this was some kind of training footage, as it's stated to be in the thread topic, I'd like to see more than 20 seconds. Where to come down from, alt, speed, distance you shot from, etc, etc. We saw the angle, sort of, but nothing more than that.
As I previously stated, IMO 20 seconds of blurriness doesn't do your intro justice... That's all I was saying. Thanks for posting.
