Vrillon ETI, 1977 Television Hijacking Incident (czech)

On Saturday, November 26, 1977 in the United Kingdom, a mysterious voice performed an illegal broadcast on live television during the height of an evening news program. The illegal broadcast was investigated by UK authorities who were unable to determine the source of the signal or who might have sent it. It would later be confirmed that five major transmitters were hijacked simultaneously, a rather spectacular feat at the time that would have required considerable transmitting power and a coordinated terrestrial effort.
