What about the eleven witnesses that responded to the author(s) of Scientific American's article dated April 7, 1906?
I have already answered this question.
See:
http://www.pprune.org/aviation-histo...ml#post8506695 and read it carefully.
Those eleven witnesses do not appear with their names excepting one, Charles Webbert, who saw the machine "
being assisted in starting on the rail". He did not mention hands pushing the airplane. Anyway, for reasons already explained the credibility of this man is zero.
