Dr. Krevor has nearly 20 years of experience leading integration across business and engineering teams to develop alternative aircraft and spacecraft technologies. His leadership has resulted in the development of new technology solutions that have been used by a variety of government and commercial customers. Dr. Krevor has experience developing new business by leading contract opportunities and collaborating with business development on Department of Defense (DoD), Defense Advanced Research Projects Agency (DARPA), National Reconnaissance Office (NRO), and NASA capture strategy, relationship building, proposal writing, and awards. He worked as an engineer on the Lockheed Martin Orion program and as a member of Lockheed’s Altair Lunar Lander team. He was also a Chief Systems Engineer on the Sierra Nevada Corporation’s Dream Chaser program. He provided technical leadership for Sierra Nevada’s Space Systems Advanced Development group, leading to multiple business awards. Prior to becoming the President and 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 while helping to win new business.

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. He 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.
