Back in September of 2018, Destin from the Smarter Every Day youtube channel met Tory Bruno, the CEO of United Launch Alliance, at the launch of the Parker Solar Probe. They obviously hit it off, and he had the good fortune to be offered a personal guided tour of the Delta IV Heavy launch pad. He's since reached out to Tory again, and was offered an incredible opportunity to take another personal guided tour, this time at ULA's rocket manufacturing facility in Decatur, Alabama. With cameras. And Tory with him every step of the way, answering every question he was legally allowed to. He also drops a few nuggets of info regarding ULA's upcoming launch plans that nobody knew about. Anyone with an interest in spaceflight, precision engineering and/or high-end manufacturing processes really should watch this, regardless of how you feel about the "Old Space" consortium and competitors like SpaceX. The level of access is unprecedented, the footage is fantastic, and Tory seems like the most knowledgeable, approachable and just-plain-likeable CEO that I've ever heard of. There's another shorter video on the second S.E.D. channel with some additional footage, where Tory answers some broader questions about engines, re-usability, competition, and the rocket business generally. Also well worth watching.
