Late entry: Scout HG demo

[mcelrah]

Two weeks go, Brian Vant Hull delivered his inimitable lecture on
hang-gliding to my son's scout troop. (I performed the Vanna White
role, helping to set up the glider in the church basement, putting
scouts in harness, helmet, etc.) An Eagle Scout, veteran high school
physics teacher and HG observer, Brian is uniquely well-qualified to
do this. He used this as a teaching moment to get a lot of physics
into the scouts heads. Now if we can just get a hang-gliding merit
