Elon Musk's SpaceX drops lawsuit against Air Force

Musk's SpaceX filed the lawsuit in the U.S. Court of Federal Claims in April after Boing Co. and Lockheed Martin Corp. landed the lucrative deal through United Launch Services. Musk contended the Air Force set up a bidding process that gave United Launch an unfair advantage.

Court records show former U.S. Attorney General John Ashcroft mediated the settlement talks.
