AUDIO: Narrator: With Duke acting as photographer and Young as driver, they put the rover through a full test. Duke: Man, you are really bouncing. Houston: Is he on the ground at all? Duke: He's got about two wheels on the ground. OK. Turn sharp. Young: [Laughs] I have no desire to turn sharp. OK, here's a sharpie. Duke: Hey, that's great. He's got a big rooster tail out of all four wheels and as he turns, he skids, the back end breaks loose just like on snow. Come on back John. Hey the (deck?) is running. Man, I'll tell you, Indy's never seen a driver like this. OK, when he hits the craters, it starts bouncing and that's when he gets his rooster tail. He makes sharp turns. VIDEO DESCRIPTION: Footage taken by Duke, some ways away from Young driving the rover.
