This is an interesting story; if you saw the movie End of the Spear, it is a compelling story. Steve Saint is the son of Nate Saint, one of the missionaries martyred in 1956 trying to establish contact with the Waodani (Auca) tribe in the Amazon jungle. If you want the whole story, go rent End of the Spear, and get a box of tissues while you are out.
Here are the details, and here is a video of the car/plane in action (you have to sit through a short ad first).
The FAA has certified the device, the first time a flying car has been so recognized. Wow!
