One of the first tests of his emerging ideas came from another GMAP veteran, Erik Modisett, F08, who works for the U.S. Customs and Border Patrol. Modisett's agents had intercepted a drug-running drone; could Kovar learn anything from it?

By that time, Kovar had already developed software to analyze data in autonomous vehicles like drones, and he set to work. "We were able to tell them that it wasn't just this one flight," Kovar said. The people running the drone "had been doing this for several months, and we found places they were flying, and one was a house where they were doing tests of the drone. We said, you might want to go to that house."
