THE IDEA

A modern twist on a century-old approach

Our vision is for electric aircraft to play a pivotal role in the future of aviation. Electric aircraft fly with zero emissions, are highly efficient and cheap to operate. However, given the low energy density of batteries, they’re only able to fly short routes with few passengers. Magpie Aerotowing overcomes this limitation by using a network of tow aircraft to enable long-range electric flight.

Aerotowing – the approach of towing one aircraft with another – has a century-long history in aviation and is used in glider flying today. Magpie Aerotowing extends its applications across electric aircraft, eVTOLs, and military aviation.
