Epochal Historian
Peter,
Just a small correction. Two hundred and four years ago, not 104 years ago, Sir George Cayley was deep into developing aeordynamic physical theory (lift vs. drag), air screws (propellers), wing and tail surfaces and building scale and full scale aircraft that were able to accomplish heavier-than-air flight. Throughout the 19th century different power plants (mostly steam) were used to power such aircraft. The real problem was to develop a power plant that had sufficient power to lift both the aircraft and a pilot. The Wright Brothers were able to utilize the new gasoline engine and light weight bicycle parts to realize the power to weight ratio necessary for manned flight.
True, there were some scientists circa 1900 who didn't believe it possible but they hadn't read the literature that had been available, at least in Great Britain, for a century.
of course, a hundred and four years ago our best scientists were almost 100% convinced that heavier-than-air flight was impossible,
