Agusta Westland is currently flight testing the AW609 for the civilian market expected to start certification in 2020
On 6 December 2002, the first ground tests of the BA609 prototype began. So 18 years to get to start certification. How long will certification take for the first civilian tilt-rotor?????
Uber don't even have a mockup of a concept vehicle yet.
I think way too many people think that if you develop an App, the problem is solved.
