Although the company has flown its pre-production prototype already in a controlled setting, this new approval to fly production-line aircraft is a big milestone and will pave the way for Joby's first sale to a customer. That customer is the U.S. military; Edwards Air Force Base will be taking the aircraft in 2024 to be used in logistics applications. Joby's contract with the U.S. Air Force is worth $131 million, according to the press release.
