There is a movie documenting Richard Bach's late-70's barnstorming trip
around the country with a pair of Fleet biplanes (same name as the book,
but I cannot remember what the title is). In one segment, he attaches
flares to the wingtips and goes flying, ignites the flares and in the
course of the flight, stalls and spins the aircraft. It is at this point
the a picture makes clear what is happening with the wings.
The smoke from the flare on the outside (flying) wing streams behind the
wingtip, while the smoke from the flare on the inside (stalled) wing
wafts slowly upward. This was filmed from the air from the accompanying
aircraft.

It would be more helpful if someone placed the smoke generators about mid-span
so that the smoke passed over the wing. That would be a much more accurate
indication of how well the outside wing was actually flying.
