Second DAR here. You don't need a video, you don't need to invite your friends to watch. I did my first solo in 1981 and I can remember it very well. Enjoy it, you really only do one first solo. I've flown a lot of other stuff (gliders, balloons, microlights) since then but the first is special. Much better than losing my virginity, and I don't have a film of that either.
