ORAC, 10/10 to Dizzy for balls, but as your signature says, think of the danger of real knowledge.
If the press think being immovably trussed to a rigid pole by 5 tonne webbing is wing walking then I'm an astronaut, and that slimy oleagenous filth they advertise really is butter and not some vile variety of margarine.
On the other hand the "wing standing" is just a simple safe stunt. A sack of potatoes could do it. The quote left out of your report related to some girl who wowed crowds in the '20s by doing the Charleston on the wing af an aerpolane (probably a Curtiss Jenny). From the film I've seen I very much doubt she was more than tied on with a lose rope, if even that. Now thats wing walking, thats bravery (or stupidity).
Even so, how wonderful to see an Octogenerian with such a zest for life. Whatever you call it Dizzy's stunt is dead impressive!
