Unalaska, AK – Yesterday, the tug boats Gyrfalcon and James Dunlap responded to a distress call from the Shell Oil motor vessel Nanuq. Don't worry, though - it was just a drill. The City of Unalaska, the Coast Guard, and the Alaska Department of Environmental Conservation teamed up to test out the emergency towing system. The point of the ETS drill is to make sure responders are prepared for any emergencies that happen on the water, given that vessels can often find themselves in risky conditions here. KUCB's Alexandra Gutierrez has more.
