What I like about these vids is that every time I watch them, something clicks that I'd missed before. Also I like the informal commentary style. Don't take this the wrong way - You obviously know what you're doing, but sometimes you sound like an absent minded professor - e.g.
"Ok - so this contact here is an Akula and he's really moving - and then we have a cruise ship and a freighter and wow! the sea state is really ridiculous - Ok - anyway so let's look at how fast the freighter's moving - Oh my gosh it's really close - and is that another hostile submarine? - Anyway, this is how we use the DEMON....."
I have visions of a first officer in the control room trying to catch your attention - "Er.. Sir? If we could just get back to the Akula? You know, the big deadly thing that's looking for us too?..."
First rate work anyway - Thanks for taking the time
