Inside the race to build hybrid electric airplanes
We've all gotten used to the idea of electric cars, but now companies are trying to build viable electric airplanes. Last month, the company Zunum Aero took a big leap forward, when the charter flight firm JetSuite said it was purchasing up to 100 of Zunum's still-to-be completed aircraft by 2022. With other major backers, Zunum Aero is considered best positioned to make it faster, cheaper, and greener to fly. Dana Jacobson reports.
