All-Electric Flying Car Gets Go-Ahead for Testing

Ally Winning, European Editor, PSD

“I was told we’d all have flying cars by now” is a common put down among those cynical of potential technological advancements. Up until now, they may have had a point, but with the news of the FFA granting Alef Aeronautics legal permission to test its Model A vehicle both on the road and in the air, they ma
