Opponents of a proposed launchpad for commercial rockets on the Georgia coast are asking a court to throw out the project’s government license, saying the Federal Aviation Administration failed to correctly assess the risks of firing rockets over homes and a barrier island popular with tourists.

Attorneys for the Southern Environmental Law Center filed suit in U.S. District Court seeking to revoke the launch site operator license the FAA granted in December to the planned Spaceport Camden. Officials in coastal Camden County have spent the past decade and more than $10 million seeking to build a spaceport for launching satellites into orbit.
