Will giant drones one day ferry us all through the heavens all on our way to and from work? Jane Wakefield speaks to two German companies who are working on that vision.

Daniel Wiegand, co-founder of Lilium, says his company's sleek battery-powered creation can neither be seen nor heard as it whizzes through the air - which apparently is a good thing. Meanwhile Alexander Zosel, founder of rival Volocopter, assures Jane that commuters will be perfectly safe as they are raised aloft in his pilotless aircraft.

But aerospace analyst Richard Aboulafia questions whether these services will ever be affordable to the average bus or train passenger. Plus Jeremy Wagstaff.
