Elon Musk is once again feuding with Jeff Bezos' Blue Origin, this time over efforts to restrict SpaceX's Starship launches.

Blue Origin wants the US Federal Aviation Administration (FAA) to cap Starship launches at Florida's Kennedy Space Center. Musk's response: "Sue Origin."

"An obviously disingenuous response," Musk tweeted. "Not cool of them to try (for the third time) to impede SpaceX's progress by lawfare."
