But yes, quick delivery for organs is great - if this is enough commercial demand to make a drone superhighway worthwile/viable though is another question. Also these drone superhighways drop at a specific point at the end of the highway - so you still need to pick it up from the superhighway 'Skyway hub' and get it to the end customer.

When I looked at the Coventry Skyway project last it looked like it was started by a team who had nearly no experience in aviation or logistics so it did make me a bit sus.
