"How will I help you today, Mom?" asked Robin, eager to get started. "We will fly three different landing approaches. You will work with Ruth in the computer lab. She will explain what to do. You will keep track of how loud each approach is. As the microphones from the airplane receive the sound from the helicopter, a computer will record the sound. I'll call you on the radio when we are ready to begin the flight test." With a pat on Robin's shoulder and a smile, Jackie Whirlybird left the computer lab for the helicopter.
