Lilium – Lilium is a new ultralight two-seater electric plane concept, designed by four German engineers.
Vertical take-off and landing – Its swiveling ducted fan engines would allow it to take off and land vertically, requiring only 15 square meters of flat land to do so.
Everyday aircraft – Co-owner Daniel Wiegand says, ""Our goal is to develop an aircraft for use in everyday life. We are going for a plane that does not need the complex and expensive infrastructure of an airport."
Fair-weather flying – It's designed to only be flown in good weather conditions in daylight. It also needs uncongested airspace.
When might it launch? – The full-size unmanned prototype is planned for later in 2016, while Lilium hopes to make the plane available for sale in 2018.
And the price tag? – There's no price named as yet, but a release by the European Space Agency promises that it'll be "far less than similar-sized aircraft of today and with much lower running costs."
New waves – Lilium is part of a fresh generation of design-led light aircraft shaking up an industry with new concepts -- like the Icon A5, pictured.
Foldable seaplane – Launched last year, the Icon A5 is a two-seat, foldable seaplane. It's so compact it fits in most car garages and can be towed behind a vehicle for overland transport.
Recreational aircraft – The Icon A5 is primarily a recreational aircraft. It can be flown by anyone with a sport pilot license.
Costs less than a house – The Icon A5's base price of $197,000 base rises to $247,000 with additional features. The company says it has received over 1,800 orders.
Cobalt Valkyrie-X – Currently available for pre-order, the Cobalt Valkyrie-X is a piston-engined light aircraft designed by French-born California-based entrepreneur David Loury.
Not just a pretty design – The Valkyrie-X's main purpose is moving people over relatively long distances. It's capable of flying five people from London to most of Western Europe without refueling.
Costs less than a much nicer house – The Cobalt Valkyrie-X starts at $699,000 -- more for extras. Cobalt is currently rolling out its first test aircraft.
Burt Rutan's SkiGull – Inventor and aviation legend Burt Rutan has developed the SkiGull, an amphibious seaplane with retractable skis.
Rutan's last creation? – "It will be the last time I design and build an airplane, since I want to enjoy this one for myself," says Rutan, 72. "I will explore the world with it, visiting the places you cannot easily get to any other way."
