Simplex asks - In a time when the longest flight in France was just 220 meters, W. Wright, who had claimed he had flown 24 1/5 miles in 39 minutes, on Oct. 5, 1905, came to Paris to search for a plane engine?!
Seriously?! (note the similarly emphatic punctuation). Let's just assume what you say is true.
Given your base concession that the Wrights "had flown 24 1/5 miles in 39 minutes, on Oct. 5, 1905," and with an apparently less capable engine, how does their searching for a more capable engine in 1907 imply anything sinister about the truth of their prior flights?
An invention that succeeds to some impressive extent with lesser components can do even more with better components, non?
