Elon Musk has called for the cancellation of Verizon’s $2.4 billion contract to upgrade the Federal Aviation Administration’s air traffic control system, following reports the FAA is close to reassigning the work to Musk’s internet satellite company Starlink. Last week, Musk shipped about 4,000 Starlink terminals to the FAA. That prompted criticism from Massachusetts Democratic Senator Ed Markey, who said the move “creates an appearance of a conflict of interest.” Last month, Trump’s Transportation Secretary Sean Duffy announced he’d assigned SpaceX engineers to “modernize” U.S. air traffic control systems following the deadly crash of an American Airlines flight as it approached Washington, D.C.’s Reagan National Airport.
