Flyable Porsche as opposed to a roadable airplane.
Structurally speaking high buck cars and airplanes are
converging. This is about what I had in mind for a roadable
aircraft fuselage. The weight on this chassis is 175 pounds
plus 45 pounds or 220 pounds.  Not bad for a fuselage.

Also in this article I might add Porsche got it right for weight
distribution and aerodynamic down force distribution. See the attached
OCR text. This correlates well with what I said back in 1968.

It is hell to be 40 years ahead of your time :)

Mazda and the dumb automotive press are still hung up on
50:50 weight distrubtion. What they should have done is move
the Mazda 3 power train to the back of the Miata. The next
thing after that would be a front drive Mazda 3 with a rotary
and then a new mid engine rotary powered sports car.

But no... what we get is a warmed over 1950's English sports car
with a four cylinder boing boing..


HIGH-PERFORMANCE Composites July 2005
"Aerodynamics and downforces One of the main considerations for a race car design is aerodynamics, two components of which are lift and drag. At the Carrera GT's top speed of 330 kph/205 mph, aerodynamic lift forces could significantly reduce stability. To develop sufficient downforce without creating a negative influence on the car's drag coefficient, Porsche designed a carbon fiber underfloor cover based on its years of racing experience and then optimized it in wind tunnel trials. The carbon undercover is bolted to the chassis, engine frame and stainless steel crash structure, and features diffusers, ventilation channels and air fins. The system, which includes the undercover, front air ducts and rear automatically adjustable spoiler, is designed to ensure not only strong downforce (4,000 Newtons/900 Ib), but an optimum 30:70 distribution of downforce between front and rear axles, respectively."
