The Lilium also features a computer-assisted piloting system that will require only 20 hours of training, designers say -- although presumably aviation authorities will have something to say about that.
According to a report in the U.K. publication The Telegraph, the Lilium would be classified as a Light Sport Aircraft, designated to fly in uncongested airspace to a maximum altitude of three kilometers, or just under two miles.

More details from the Lilium's online spec sheet: The aircraft will have a maximum velocity of 250 mph, with a maximum takeoff weight of 600 kg, or just over 1,300 lbs. Designers are aiming for a range of about 500 km, or around 300 miles.
The Telegraph article notes that, in Europe at least, flying the Lilium would require clearance from the Civil Aviation Authority (CAA), which would also need to grant permission over any landing site. So while you couldn't take off from your front yard, you could use your friendly neighborhood helipad facility. Or, naturally, an airport.
Here in the United States, aviation company Terrafugia announced that its prototype TF-X flying car will be ready in two years.
Lilium Aviation is run by a team of designers from the Technical University of Munich and has received funding and support from both the European Union and the European Space Agency. Oh, and they're hiring.
