The world that wasn’t – past visions of aviation’s future

Aviation is poised to enter a bold new era of superjumbo jets, low-emissions engines powered by algae and commercial space flight.

The gallery includes everything from Leonardo da Vinci’s flying machines to several versions of the flying car.
