Frank,
thanks for all this information!
however I would like to know of the aerodynamic features of soaring,
what happens to the angle of attack relative wind etc... when

Think of a slinky spring going down stairs.

Now think of a slinky spring going down an "up" escalator.

In short - nothing fancy happens to the angle of attack. The glider
keeps on going down through the air.

That is one damn fine metaphor! I'm gonna save that for future
