Yes this gentleman has been spouting on the key forum as well,seems to have an angle/grudge against the Wrights,I am sure the Wrights would agree that the 1903 Flyer was not perfect but one of their flights on dec17 1903 has been deemed by the FAI as the first controlled/practical power flight (or similar wording).
He was even casting doubts on their 1905 Flyer - which was a much improved aircraft...somebody has to have been first and even if you didnt like the 1903 Flyer - then the 1905 one should help redress the balance by flying for 30 mins (from memory) ... still far ahead of any other contender.
The Wrights tackled the whole thing in a much more scientific and common sense way than any other team/person.
Sure they were not perfect and got too embroiled in legal cr@p and were slow to adopt wheels but other than that they ended up with a very practical flying machine by 1905 !
