Elon Musk's SpaceX launched a pair of Falcon 9 rockets loaded with a combined four dozen Starlink communication satellites into space Tuesday morning from both U.S. coasts.

SpaceX halted the launch of a Falcon 9 rocket on Sunday with 11 seconds to spare after a plane allegedly flew into restricted airspace near the launchpad. The California exhibition set to send Starlink satellites into orbit fell apart at the last minute when an aircraft encroached on the rocket’s launch space,
