In written testimony, Cathy Cahill, director of the Alaska Center for Unmanned Aircraft Systems Integration (ACUASI) at the University of Alaska Fairbanks, said that while more testing needs to be done to improve counter-UAS (C-UAS) technologies, including detect, track and identify (DTI) drones, mitigation operations should remain in the hands of federal authorities. In 2021, the FAA announced the selection of five host airports — Atlantic City International Airport in New Jersey; Syracuse Hancock International Airport in New York; Rickenbacker International Airport in Columbus, Ohio; Huntsville International Airport in Alabama and Seattle-Tacoma International Airport in Washington state — to evaluate technologies to detect and mitigate potential safety risks posed by unmanned aircraft.
