FAA issued a Certificate of Authorization (COA) to Kansas State University to fly the PowerCat, a gas-driven unmanned aerial vehicle, above Crisis City, an emergency response training area near Salina, Kan. This is the second COA issued to K-State. The university said the ability to fly over Crisis City opens the door for more extensive training in search and rescue operations through use of sites that include a simulated disaster-struck city, crashed transportation vehicles and a collapsed building.
