"Mark my word: a combination airplane and motorcar is
coming. You may smile, but it will come." – Henry Ford,
1940.
At the time Henry Ford spoke these words, imagining the year
2019 may have conjured predictions of a world filled with
technologically-advanced civilisations colonizing other planets
and, in Ford's mind at least, travelling in flying cars.
Whereas it is likely that Man will step foot on the surface of
Mars in the next few decades and perhaps form a Martian colony
within the next century, the idea of flying cars seems as
futuristic and far-off now as it must have done to many in
1940.
The technological hurdles to overcome in designing a
commercially-viable flying car are numerous and any potential
design needs to answer many questions.
