Nikola Tesla has given a lot to today's society and his inventions should be respected more. Tesla was a man far ahead of his time, and his countless inventions are evidence that this man was in fact the most incredible inventor to ever live on Earth. If it wasn't for this man, things like smartphones, radio, remote controlled devices, etc… would be something completely unknown to us. Tesla was onto great things, technologies that most scientists today cannot even imagine. In 1928, Tesla registered yet another patent: number 1,655,144: A flying machine that resembled both a helicopter and an airplane. Before his death, Tesla had developed the blueprints for the propulsion system of his aircraft. He called it "SPACE DRIVE" or the anti-electromagnetic field propulsion system. Interestingly, according to William R. Lyne in "Occult Ether Physics", in a conference that Tesla had prepared for the Migrant Welfare Institute on May 12, 1938, he spoke about the Dynamic Theory of Gravity. Tesla
