I guess many on here have flown a Hang Glider (not a paraglider) - for those that have not that vid is totally representative of a HG take off but about 50% faster.
The wind noise is the same as is the 'off a cliff' sensation (in nil wind conditions).
The way the sight picture works out is the same but I suspect his glide ratio is somewhat less than a HG (13:1 ish on HG).
