Jean Floyd is CEO of Stratolaunch, which aims to make access to space more convenient, reliable and routine. Floyd has more than thirty-eight years of industry experience and is uniquely qualified to oversee and lead the testing and evaluation phase of the carrier aircraft.

Floyd is a seasoned aerospace professional who has experience leading air launched space vehicle, launch operations, and spacecraft programs. A graduate of the US Air Force Academy and with a Masters Degree in Engineering Management from Florida Tech, Floyd’s legacy in space began on active duty in the Air Force and continued as the program manager for Orbital’s Pegasus system. Most recently, Floyd was vice president and general manager for the civil and defense division at Orbital ATK, where he managed P&L responsibilities of Human Space Systems, National Security Space, Science and Environmental, and Advanced Flight Systems.

Dr. Zachary C. Krevor is the Chief Operating Officer at Stratolaunch. Dr. Krevor is responsible for overseeing many of the programmatic and operations functions of Stratolaunch, including oversight of the carrier aircraft, conversion of the carrier aircraft into a mobile launch platform, and leadership for many of the business functions.

Dr. Krevor has a M.S. and Ph.D. in Aerospace Engineering from the Georgia Institute of Technology. He received his B.S. in Mechanical Engineering from UCLA. Dr. Krevor has experience with a wide range of spacecraft and launch vehicle programs. Dr. Krevor worked as an engineer on the Lockheed Martin Orion program and as a member of Lockheed’s Altair Lunar Lander team. Prior to Stratolaunch, Dr. Krevor was a Chief Systems Engineer on the Dream Chaser program for Sierra Nevada Corporation. Dr. Krevor also provided technical leadership for Sierra Nevada’s Space Systems Advanced Development group. Prior to becoming the Chief Operating Officer at Stratolaunch LLC, Dr. Krevor was the Vice President of Engineering at Stratolaunch Systems Corporation, with leadership responsibility for launch vehicle development and integration with the carrier aircraft. Dr. Krevor is an AIAA Associate Fellow, a member of the Space Systems Technical Committee, and a private pilot.

Dr. Daniel R. Millman is the Chief Technology Officer at Stratolaunch, and has extensive experience in hypersonic aerodynamics, hypersonic vehicle design, and flight test.

As a Chief Engineer at Booz Allen Hamilton, Dr. Millman was named an Engineering Fellow for Hypersonics and co-lead the Hypersonic Working Group for the firm. He has worked with the Air Force Research Labs to design new concepts for an extended range, maneuverable hypersonic reentry vehicle.

Dr. Millman received a patent for a flight control system using a flush air data system that is usable on various aircraft and missiles, including hypersonic re-entry vehicles. He designed an autopilot for an agile missile concept using reaction control jets for rapid turns. He also advised the USAF on conceptual design methodologies for advanced aircraft, as well as tactical and cruise missiles.

Dr. Millman served in the US Air Force as a B-52H Instructor Pilot and Air Force Test Pilot. He graduated from the USAF Test Pilot School (TPS) in 1998 and was the project pilot for the Advanced Weapons Integration Program on the B-52H. In 2004, he graduated from the Air Force Institute of Technology with a Ph.D. in Aeronautical Engineering. His three years of research led to four journal articles, four conference papers, and a session keynote address at an international conference. After earning his Ph.D., Dr. Millman returned to Edwards AFB where he instructed at TPS.

Besides classroom instruction in compressible/hypersonic flow and modeling and simulation, Dr. Millman taught multi-engine flight test techniques in the B-52H and the C-12C. He was chosen to be the first director of the Hypersonic Combined Test Force (CTF) in 2006. His CTF was responsible for ground and flight testing of the X-37A, X-51A, and the development of the Blackswift Hypersonic Aircraft. He also conducted the first test flight of Fisher-Tropsche fuel on an Air Force aircraft – the B-52H. On May 26, 2010, he piloted a B-52H to 49,500 feet and performed the first launch of the X-51A, which set a world record for a climb using a scramjet.

As a command pilot, he flew over 3600 hours in 35 different aircraft types.
