This is the most recent free book about one of the greatest technical frauds of the twentieth century. The work is based only on primary sources, mainly documents of the period 1903-1905, in majority letters of the two brothers and the answers received by them, plus newspaper articles (all quoted in full).
After reading the letters and articles you start to ask yourself how is it possible that so many authors credit Wilbur and Orville Wright with building the first heavier-than-air man carrying plane that ever flew when, in fact, the two inventors just tried to fool the newspapers (especially those of Dayton), Octave Chanute (a personality of the aeronautic world of the time), Georges Spratt (a fellow aviation enthusiast), Carl Diesentbach (the New York correspondent of the German journal "Illustrierte Aeronautische Mitteilungen") and both the US War Department and British War Office, by pretending they had performed no less than 105 flights in 1904 and, in many instances, describing aerial trips that are physically impossible, like the ones of August 13, 1904, when the plane, Flyer II, got energy from the headwind, which accelerated the apparatus.
"The Press", the only newspaper that, on May 26, 1904, furnished a list of witnesses (friends of the Wright family and an unnamed reporter) who saw the alleged flight of the same day, later in the year, on December 17, 1904, acknowledged that nobody had ever seen the two inventors flying powered planes.
