Aaron Harrington came to the ARL as a University of Maryland sophomore and wound up spending two more summers there. "I didn't know that research was something that you could go into," says Harrington, who is now 24 years old and earning a master's degree in aerospace engineering from his alma mater. In 2008, Kroninger assigned him to photograph wings flapping, which normal cameras will capture only as a blur. Using a strobe light to combat the blur and technique called photogrammetry, Harrington used two cameras recording video at 30 frames per second. "If you had two cameras and knew how far apart they were and had some idea of the distance from the test bay," he says, "you could use triangulation to measure the distance. It turned out to be very accurate.
