No real progress,then

Since 1909, when Alberto Santos-Dumont designed the Demoiselle, a lightweight (250 pound) high-wing monoplane.

It worked a treat, and quite a lot were built by others, as Santos-Dumont had given away the drawings for free, in an early form of open-source. The drawings were published in Popular Mechanics, June 1910.

Sure, engines, airframe materials and instrumentation have improved considerably since then, but are we any closer to a personal skycar?

I doubt it.
