On watching all episodes in order, this is easily my favourite so far. A member of an advanced alien race accidentally pilots his flying saucer into Earth's atmosphere after a mishap with a meteor. After a hasty scramble across the United States the floundering UFO ditches in the ocean, which is where The Seaview comes in.

Having tracked the UFO across America, a fatalistic, trigger-happy rear-admiral is dispatched to the Seaview via helicopter with orders to destroy the submerged spacecraft at any cost.

Of course the more thoughtful, scientifically minded Admiral Nelson along with the level-headed Captain Crane would much rather tackle the problem with reason and intelligence in order to work out what is really going on.

A great example of cold-war paranoia in science fiction, the episode is captivating from start to finish as the action never lets up and it really does not disappoint.

We do get to see inside the UFO, complete with obligatory Jacob's ladder and other alien looking apparatus. We also get to see the true form of the alien visitor behind the disguise. We also learn that the nuclear-powered Seaview, apart from using rather "primitive" Uranium fissile material, does crucially also carry a few crates of Strontium-90 pellets for when they need that extra bit of 'kick'. This comes in rather handy as the alien visitor can work with this stuff, converting it to a useful fuel allowing his depleted craft to escape Earth unharmed by NATO forces. Thus averting a potential interstellar war, which certainly the human race would come out the loser.

Well, what else can I say, if you like sci-fi, aliens, nuclear power, submarines, tension, drama and the cold war, then this one has it all. I could nitpick things like the visible strings pulling the detachable transport module away from the UFO, but how can I when the model work is just so exemplary in this series. In the absence of CGI, this was just the most sensible way of filming it. The creators should be proud, they've really made some outstanding models, and the UFO is no exception. The story though is a classic. It's been done in many other variations, but not quite like this. Superb stuff.
