Guest: Diane Murphy. Topics: Rocket Racing League (RRL). We welcomed Diane Murphy of the Rocket Racing League (www.rocketracingleague.com) to the show. In our first segment, Ms. Murphy talked about the Rocket Racing League, what it is, what it has done so far and it what it will be doing in the future. She explained the air frame and the rocket engine and told us about the manufacturers of each. She also said that the air frame structure determines the performance of the vehicle, not the rocket motor.
