The auto company report said a retractable hardtop couldn't be built...
... Ben J. Smith proved them wrong.
Now he has filled these pages with his 1957 automobile design notes, drawings, and his narration of how he succeeded in creating the first successful production retractable hard top (Ford Skyliner) along with other inventions that broke boundaries and change auto history.
"Major car manufacturing companies of the world had spent decades trying to design a steel top convertible suitable for production. Chrysler secretly had designed the Thunderbolt with the roof retracting on channels but the windshield kept breaking. General Motors kept its research and development unexposed while Ford engineering spent months and $390,000 (1952 dollars) on a comprehensive report of "why it couldn't be done".
