This should be an answer to the thread proposed by champ2823 entitles Closed thread, but since it has been closed by the moderator I am starting a new one. I will not discuss the 9/11 conspiracy. I think Ivan did well in closing it. I will address some historic misconceptions of the author: Every educated person in the 15the century knew the Earth was round and they accepted the measurement made by Eratostenes in the 3rd century BICE, that is very close to the 40000km now accepted. Because of that nobody believed that Asia could be reached by navigating to west. Columbus used another estimation that gave 25000km to Earth's equatorial circumference. With this estimation Asia would be very close to Europe. Fortunately for Columbus, there was the american continent in the way, or else he and his crew would perish from lack of food and water. In the same way, people knew that the heavier than air was possible. Birds fly! The problem was of technology, not of science. And the Wright brothers were not alone in their work. Several other inventors were doing the same, including the Brazilian Santos Dement, that flew in Paris after the Wright brother's flight, but without recourse to a catapult for take off. Modern historians don't believe Nero burnt Rome. What was burnt were poor quarters of Rome and it was probably an accident favored by the fact that the quarters were composed mainly of wooden shacks. Nero has taken the opportunity to blame the annoying christians and later rebuild the quarters with mansions in marble.
