On a seemingly ordinary evening, just after 5 PM, the residents of Southern England received an unexpected interruption during their television programming. An unidentified individual, later referred to as Vrillon, hijacked the signal of Southern Television, a regional broadcaster. This unusual occurrence lasted for six minutes and was characterized by a message that claimed to be transmitted by the 'Ashtar Galactic Command'. The message warned humanity about the perils facing the Earth while advocating for global peace and harmony. Notably, the announcement featured a distinctive visual of a pulsating green triangle, which added to the surreal quality of the broadcast.

Viewers, often accustomed to routine programming, were captivated and, at times, confused by the alarming message that urged them to embrace spiritual awakening and preserve their world. The incident not only caught the attention of those in the viewing area but also reverberated through news outlets and word of mouth, mystifying the public and prompting various theories about the identity of Vrillon and the motivations behind this bizarre takeover. Various investigations were launched, but no conclusive answers about the perpetrator's identity emerged, leaving many questions unanswered.

In the following days, the event triggered widespread discussions about media security and the potential for similar occurrences in the future. It also captured the imagination of conspiracy theorists and UFO enthusiasts, linking the broadcast to the broader context of the 1970s' fascination with extraterrestrial life and cosmic phenomena, making it a significant cultural reference point in British media history.
