Tesla Motors’ Elon Musk plans to build cars that fly and swim

Elon Musk, the California entrepreneur who heads electric car company Tesla Motors and rocket builder SpaceX, wants to combine aspects of each by developing a car that can fly.

“We could definitely make a flying car — but that’s not the hard part. The hard part is, how do you make a flying car that’s super-safe and quiet? Because if it’s a howler, you’re going to make people very unhappy,” Musk told the Independent, a British newspaper in an interview pitching the rollout of a right-hand-drive Tesla Model S electric sports sedan in Britain on Monday.
