I brought all the drones down to a few feet above ground and started a search pattern for raptor prints. The drones took off in different directions, following anything that was even remotely print-like. Chivvying all these units was really wearing on me—even in frame-jack, I had to keep track of what orders each unit was following—so I guess I don’t feel too bad that it took me a couple of missed cycles before I realized one of the units wasn’t responding.
