All comers are welcome to elucidate the hang glider scene ...
I do not see a tail; or I speculate that maybe the people are picking up pieces of the tail. Not sure, just speculating.
Exact location of the scene would be interesting.
And is hang gliding occurring at the site today? Details of the Curtiss hang gliding realm is invited.
The study clip photo is from some book which we hope to discover and post the title of.
Related, but not the book source of the clip study image: http://aviation-history.com/early/curtiss.htm
Present museum: http://www.glennhcurtissmuseum.org/
One clip from a museum online page:
"In December of 1907 they elected to move their operation to Hammondsport where Curtiss manufacturing facilities would be at their disposal (Curtiss also had a business to run). "
Though Curtiss was mostly about engines, the hang gliding rub is focus of the study.
Here is something:
"1907 AEA Glider" ... could it be the same as the study photo on Finger Lakes region?
