The US government has approved multiple pilot programs that will allow electric air taxis to begin testing across 26 states.

The aircraft could include taxi and emergency medical response services, regional transportation, and autonomous flights.

The federal government announced a new pilot program designed to get new kinds of ultralight vehicles and “eVTOLs” up and running around the country—even if they’re not fully FAA-certified.

Several U.S. flights and airports were disrupted in multiple security incidents over the weekend.
