I was on Skype trying to teach a friend how to use the narrowband and the DEMON to help figure out the identity of a contact and my friend comes back and says "Okay. This target has 6 blades." and I was like "What !?! That target should be a container ship ! What the hell is he targeting !?!" I thought he had wandered off somewhere and was way of target. Twenty minutes of arguing later. I picked up the ship and saw the six blades and thought something was definitely screwy. I did a close approach with my periscope and saw that the target was indeed the container ship.
