Tell your friend to learn about dynamic soaring- they go a lot faster than 40mph! See: http://en.wikipedia.org/wiki/Dynamic_soaring

Ya beat me to it. I've heard in excess of 100mph. Pretty impressive stuff for a plane without and engine.

Wind has nothing to do with the actual speed of a glider, wind only creates the lift, more wind, more lift

Slope basics
Wind hit the slope, that creates "Lift" ,, Lift is the column of air that the plane falls/glides through
Speed is created by the glider continually diving through this column of air, This controlled dive propels the glider forward more than down

The secret is finding that balance so you can continuously maintain altitude while diving as fast as you can.

edit, just watched that vid,, that's crazy fast,,

wind speed can and will increase with canyons and gulleys, combined with mountains hills...just like wind blowing down a street lined with sky scrapers.....add gravity
