As the broadcast did not affect the video signal, it was difficult to detect its source, and the transmission disappeared at the end of what sounded like a prepared statement. Most observers have concluded that the broadcast was a hoax, achieved by directing a powerful signal at the Hannington UHF transmitter.
At the end of what engineers later described as a "rogue transmission", as the signal faded back, various random sound clips are heard (which are most likely picked up from other channels), such as the Looney Tunes cartoon theme song and the Art Davis cartoon "The Goofy Gophers". In addition, other music can be heard along with what sounds like an explosion and various weird noises.
The broadcast is presently a footnote in ufology and does not represent a particularly significant development in pirate television broadcasting, supplanted largely by the boom around 1984.
