60 Minutes+ reports that government documents back up allegations that SpaceX’s Starbase test facility in Texas has violated its federal permit through excessive road closings and has encroached and trespassed on the protected Boca Chica National Wildlife Refuge.

The documents back up a claim by the environmental group Save Rio Grande Valley (Save RGV) that SpaceX has been closing the Texas state highway that runs through its operation for more than the 300 hours per year allowed under the permit from the Federal Aviation Administration (FAA). The organization sent a letter to the local district attorney outlining its concerns.
