It may sound like something from a sci-fi movie but one sector of commercial real estate could be about to take to the skies.

A document discovered by CB Insights appears to show that Amazon has filed a patent for what would essentially be a flying warehouse. The airship would act as a fulfilment centre for products which would then be delivered to customers by drones.

The centres would be cited above major metros, reducing the need for ground-based warehouses and further impact bricks and mortar retailers.

However, while a patent may be granted there would be significant regulatory and safety barriers to overcome before airborne real estate would become a reality.
