Retired U.S. Air Force Col. Scott Henderson left Space Exploration Technologies Corp. (SpaceX) after three years on the job as the company’s director of mission assurance and integration, and head of Florida external relations, a company spokeswoman confirmed.

Henderson’s departure was first reported by Florida Today. SpaceX spokeswoman Katherine Nelson confirmed the report in an Oct. 30 email, saying Henderson left the Hawthorne, Calif., company because “he got an offer he couldn’t refuse” from Raytheon Co. His last day with SpaceX was Oct. 31.

Roela Santos, a spokeswoman for Garland, Texas-based Raytheon Intelligence and Information Systems, declined to comment about Henderson.

Henderson could not be reached for comment the week of Oct. 29.

Henderson is the former commander of the 45th Launch Group of the 45th Space Wing at the Cape Canaveral Air Force Station. His exit is the latest in a series of executive departures from SpaceX. Former NASA astronaut Ken Bowersox, to whom Henderson reported, left SpaceX in December.
