6. Vanished

When a fully armed and piloted Navy F-14 disappears during a storm, the JAG team is called in to investigate all possible scenarios, from pilot suicide and terrorism to the curse of the Bermuda Triangle and UFO interference. When the plane's co-pilot surfaces, bloodied and disoriented, Harm and Mac get some new information that steers them away from Twilight Zone explanations and instead points them in the direction of kidnapping, terrorism and a hard-core militia group's plot to assassinate a PLO delegation heading for Washington by using the pilot -- and his plane -- to do the dirty work.
