On this episode, former U.S. Air Force B-52 Stratofortress pilot Daniel "Doc" Millman, Ph.D, now of Stratolaunch, joins guest cohost Ken Katz to discuss the challenges of hypersonic aircraft design and flight, and how the U.S. military compares to other nations developing hypersonic aircraft and weapons.
