Billions of dollars worth of private capital investment is flowing into the development of electric vertical takeoff and landing (eVTOL) aircraft, spurred in large part by the futuristic, Jetsons-like vision of air taxis moving people around heavily congested cities. How much realism is there to this vision, and what other, perhaps more likely, applications will we see for these eVTOLs?Brian Garrett-Glaser, managing editor of Vertical's sister publication eVTOL.com joins Rotor Radio to discuss air taxis, the possibilities of electric propulsion, technologies emerging from the sector and how these aircraft will augment helicopters.
