00:00The United States continues to lag behind in the global hypersonics race, but a new missile could
00:04change that. Last September, at a military convention, the Air Force Research Lab debuted
00:08a new missile called the Angry Tortoise. It features an innovative engine called Draper,
00:14which could help it change trajectory during flight. Draper meshes the benefits of solid
00:19and liquid engines, meaning it's less volatile, making it a suitable candidate for on-demand
00:24launches. So could the Angry Tortoise, despite its name, be the United States' first true
00:29hypersonic missile and travel at five times the speed of sound?
