CNBC reported that Sean Cassidy, Amazon’s chief liaison to the Federal Aviation Administration, said in an internal memo last week that it was his last day.
Since 2015, Cassidy has worked to get approval for drone deliveries. In August, the FAA, at Cassidy’s request, lifted a requirement that drone operators can see the drones at all times. That restriction, among others, put Prime Air way behind expectations earlier this year.
