Electric airplane towing concept could mean longer zero-emission flights

Magpie Aviation announced a novel new approach to electric airplanes on Monday. Today's battery technology (including CATL's new, more efficient one) severely limits the practicality of zero-emission aircraft, leaving clean-energy innovators with two incomplete options: flying a plane full of batteries or one full of people -- but not both. So the California-based startup wants to tie them together, extending the rear plane's range by hundreds of miles. Towing planes isn't a new concept, with mi...
