There's a decent YouTube video put out by a guy who has a lot of 5 minute basic rule explanations. JR Hobbes, or something like that.
I checked out the glider video before my first glider scenario and it was very useful.
A fellow named David Gala'n had put together a nice two part cheat sheet on air-drops and glider drops a few years back. Unfortunately I can't find it in my retained documents (probably lost it on a computer upgrade or something-only hard copy & in pretty sore shape here) so I'm sorry I couldn't be of an assist there. Perhaps try the French ASL site?
