The name of the expert quoted in the briefing, Werner Dahm (https://www.aiaa.org/Secondary.aspx?id=15445 https://www.aiaa.org/Secondary.aspx?id=15445), rung a bell. He seems to be the son of an earlier Werner Dahm, the one who helped develop the Saturn V rocket, and who was before that the youngest of Wernher von Braun's team at Peenemunde.
