Supersonic commercial planes are making a comeback, but it may be only high flyers that can afford them.

For everyone else, our cities could soon drastically change as flying cars (but not as we imagine them) are set to extend the reach of our cities and slash commute times.

UNSW senior lecturer in aerospace design, Dr Sonya Brown, and sustainable aircraft designer Andrew Moore join STEMM journalist Neil Martin to talk about the future of flight. They also debunk myths about hydrogen fuel dating back to the Hindenburg blimp disaster, discuss the use of drones to save lives by fighting bushfires, and explain the tricky balancing act needed to make flying more sustainable.
