"... but the Flying Sub's my baby!" Captain Crane to Chief Sharkey Seaview's reactor is running wild -- again. Without taking the time to don protective anti-radiation gear, Captain Crane runs into the Reactor Room to shut down the pile. An explosion renders him unconscious. Although treated in Sickbay with a special anti-radiation device, the Captain does not come out of his coma-like state. Doc can find no explanation. (Apparently, Doc hasn't read the script.) Corpsman Mallory has turned that life-saving device into a time-machine. Mallory is testing his fourth-dimension gadget on Crane before using it to enslave the entire world! A warped and insane Captain Crane from the future shoots and kills Admiral Nelson, because he believes the Admiral has held him back from achieving all he should have. Maybe he's paying Nelson back for the Krueger incident.

Season 4 - Episode 9 - Aired 11/19/1967

Seaview is on the lookout for an enemy sub and its underwater sub-pen. Sonar picks up a contact. The rogue sub fires at Seaview, which is saved only by virtue of her new electronic hull shield. Not so fortunate is Captain Crane, who has just located the sub-pen while on patrol in the FS-1. A powerful laser fires a beam at the Flying Sub, crippling the ship. Running out of air, moving in and out of consciousness, Crane is unable to give the pen's coordinates to Nelson. Thanks to the hard work of some enemy agents aboard, Seaview seems unable to rescue the Captain. Worried about Crane trapped in the Flying Sub, Admiral Nelson is particularly impatient in this episode. He constantly barks at Morton and the Chief. One of the enemy agents, Marco, a crewman we have seen in many other episodes, is never found out, and apparently keeps his job on Seaview!

In an attempt to control the planet's tides, Dr. Randolph Mason (a nut if ever there was one -- he is part scientist, part make-up artist!) has invented a powerful electromagnet and established a magnetic field around the moon. The only person who seems to recognize the obvious danger in this silly plan is Harriman Nelson. At first glance, it would appear that Nelson has killed Dr. Randolph. At second glance, it would appear that Captain Crane has betrayed the Admiral. On third glance, the moon is getting closer and closer to Earth, and will soon collide with our beautiful blue orb -- unless the Seaview can save the world. Again. * In this episode, we learn that Chief Sharkey attended Lincoln High in Coney Island, Brooklyn, New York. (There actually is a Lincoln High in Coney Island.)
