I've often wondered if there's enough lift

It's been two or three decades, but I know I've seen an article in
Soaring or Technical Soaring that discusses the feasability of a
related soaring flight technique. Specifically, the article suggested a
theoretically feasable technique involving maneuvers in the shear zone
at the edge of the jet stream. I remember thinking that it was one of
those "sure, it works in theory..." kinds of things.
