San Diego- and Bay Area-based flight pioneer John J. Montgomery received a patent for his aeroplane design and died testing one of them. He was the first person to execute a controlled, heavier than air, manned flight (he sat in it, it flew, he could steer, but had no engine.) He was partly inspired in his engineering by French-American engineering genius Octave Chanute. Montgomery Airport in San Diego is named for him.
