Jeff “Legs” Mabry has spent his life pushing the boundaries of flight—first as a decorated U.S. Air Force test pilot, and now as a leader shaping the future of supersonic aviation. As Boom’s Senior Vice President of Programs, Jeff leads the teams responsible for designing, building, and testing Boom’s groundbreaking hardware: Overture, the supersonic airliner; XB-1 the experimental supersonic demonstrator that recently completed flight testing; and Symphony, the proprietary propulsion system that will power Overture. 

A graduate of the United States Naval Test Pilot School and a former Command Pilot in the U.S. Air Force, Jeff brings deep experience from a 21-year military career focused on flight operations and developmental testing. Prior to Boom, Jeff supported Department of Defense flight testing, and played a pivotal role at Airbus in building and leading the flight test team for Vahana, the company’s autonomous electric aircraft demonstrator.

Jeff’s career in the U.S. Air Force centered on advanced flight operations and testing. His final assignment before retiring from active duty was as Commander of a flight test support squadron operating a diverse fleet of fixed- and rotary-wing aircraft. Prior to that, he served as an attached instructor at the U.S. Air Force Test Pilot School, training future test pilots in both airplanes and helicopters. He also held leadership roles as Operations Officer and Commander across multiple units, overseeing developmental testing of next-generation platforms including the HH-60G, X-47B, and RQ-4. Earlier in his military career, Jeff flew HH-60G Pave Hawk helicopters on Combat Search and Rescue missions, completing four operational deployments to Turkey and Kuwait.

Jeff is a graduate of the United States Air Force Academy and holds an MS in Aeronautics from Embry Riddle Aeronautical University. He has logged over 2,500 hours across 33 different aircraft types and holds FAA commercial and instrument ratings for multi-engine land and rotorcraft-helicopter aircraft. In his free time, Jeff enjoys spending time with his family, and competitive cycling.
