Storm (4 Apr. 1967)

In this episode, the aliens are creating hurricanes with a device that bares a remarkable resemblance to a US weapons program known as HAARP. It is the realization of Nichola Tesla's 1918 theory that with a given type of antenna array, the magnetosphere can be manipulated to do many things, including creating earthquakes and hurricanes. The current US antenna array in Alaska is more than 10 square acres in area and enlists some thirty separate antennae, each with massive individual power generators, to focus to a solid beam. In "Storm", the aliens are firing it from a fishing boat. This technology, either researched, or not, before they decided to write it into the script, was 30 years ahead of its time. This cutting-edge technology speculation far before its time, which was routinely used throughout the entire gamut of episodes, makes The Invaders the top notch series that it was, and still is. The special effects in this series were nothing less than spectacular. Some of the techniques were directly gleaned from "The Outer Limits" - but in color! - and in this episode, they really pour it on - especially when the antenna is firing.
