The Wright Brothers flew their spruce-wood plane for 200 feet in 1903. Only 66 years later, Neil Armstrong walked on the moon, more than 240,000 miles from Earth.

I'm not sure if there is a real connection here? Has any research on "flight machines" converged with rocket science? They seem not to be correlated very much or the correlation is not obvious. Do you think it might be good to advance on that point or rephrase it to show that there has been some kind of intellectual or economic speedup that caused the quick development of various technologies?
