Well, there you go, a misattributed quotation. Doesn't change the history of aviation, though, which is determined by reasonable inferences, not strict logic. So, it was Peyrey who said this (unless, of course, he was stealing the quote from Archdeacon--could have happened, and your challenge is to prove that it didn't happen that way round), but I see nothing ridiculous in the train of thought which goes:
1. We said they were bluffing, from 1903 right up to now.
2. Now we see they are not bluffing.
3. It is therefore highly improbable they were bluffing in 1903.
So, the question for you is, what were the Wrights doing between 1903 and 1908?
