OTTAWA -- The Ottawa International Airport's new drone detection system identified more than 250 drones flying in illegal airspace near the airport this spring. The airport has partnered with Indro Robotics, QinetiQ and NAV Canada to pioneer a drone detection pilot program to monitor the airspace around the Ottawa International Airport. The area is a no-fly zone for drones. "What we are seeing and reporting to Transport Canada is a very disturbing trend that requires a quick response to reverse the number of drone operators flying in restricted areas," said Mark Laroche, President of the Ottawa International Airport about the early results of the pilot project.
