Tesla and SpaceX have formed special committees to discuss a possible merger, Elon Musk said during the latter's third quarter earnings call Tuesday. Musk, who serves as CEO of both companies, said the special committees have not reached agreement on the terms of any transaction - and that there's no guarantee that they will. That said, he called the possibility of a Tesla-SpaceX merger a "good idea." "I think it would be a good idea," Musk said.
