US military developing flying car

US military commanders are considering procuring flying cars to transport troops around the battlefield.

We’re finally getting flying cars??? OMG!!!

We’re finally getting flying cars??? OMG!!!

We might finally get to scratch “flying car” from the list of stuff Popular Mechanics promised us we would have by the year 2000. A Massachusetts-based company called Terrafugia is set to test a nice little flying car prototype that can transform from a two-seater to full flight mode in about 15 seconds.
This design has quite a few innovations. First, it flies and drives with the same engine, hence it uses regular car fuel for flying. Terrafugia claims it will be able to fly up to 500 miles on a single tank of gas at a cruising speed of 115 mph. Second, the whole thing fits inside the car body. Terrafugia’s top chief Carl Dietrich said, “This is the first really integrated design where the wings fold up automatically and all the parts are in one vehicle.”
If the tests are successful, the company hopes to have the production model hitting the street in some 18 months. And all of us nerds that daydream about flying over those damned traffic jams will smile.
