President Joe Biden wants private space companies, such as Elon Musk's SpaceX and Jeff Bezos' Blue Origin, to start paying taxes to use US airspace.

"Whenever SpaceX launches a flight, it requires massive air traffic control resources to clear the airspace for hours around the launch window," David Grizzle, a former chief operating officer of the Air Traffic Organization, an agency within the FAA that hires the controllers, told The Times.

"And again, it pays zero," he said.
