But if the goal of this Special Project was to reboot the canceled Schiphol Airport Eagle vs. Drone project, then there were ways he could be of service. First of all by building practice drones, the sole purpose of which was to be ripped out of the air by eagles, using rotors with pivoting blades that would be less likely to damage the feet of an attacking eagle. These would make it possible for the falconers to train their eagles safely.
