FAA warns SpaceX it has not approved new Texas launch site tower

The U.S. Federal Aviation Administration (FAA) has warned Elon Musk's space company SpaceX that its environmental review of a new tower at its Boca Chica launch site in Texas is incomplete and the agency could order SpaceX to take down the tower. An FAA spokesman said on Wednesday that the agency's environmental review underway of SpaceX's proposed rocket assembly "integration tower" is "underway," and added that "the company is building the tower at its own risk."

SpaceX did not respond to a request for comment.
