CP-140 Aurora

It's been called one of the greatest submarine hunters in the world, and it's still one of Canada's best-kept secrets: the CP-140 Aurora. This Cold War legend remains a state-of-the-art spymaster, flying 17 hours straight to find ISIS targets in Iraq or exposing illegal traffickers around the globe. The Aurora must prove it still has the right stuff in an exercise to search for a mock submarine hiding in the Georgia Straight of the coast of British Columbia -- but her flight crew finds some unexpected obstacles.
