"Vrillon" 1977 Television Hijacking Incident

This is the audio to a television hijacking incident from November 26, 1977 in the United Kingdom, ten years before the Max Headroom pirating incident in Chicago. Someone, or something, interrupted an ITN report claiming they were an alien named Vrillon, and was saying that we need to get rid of weapons and such. It was mixed with lots of static, and was a rogue transmission (you could hear audio from other stations). Only the audio of ITN was interrupted. The video stayed the same (unfortunately, I only have the audio). The hijacker was never found.
