PALMA DE MALLORCA. -- According to the "Diario de Mallorca", "Everything went haywire" at the US-Spanish tracking space station in Puigmajor, Mallorca, as numerous unidentified flying objects were detected.
The newspaper, which cites technicians at the station, claims that the radio receivers were jammed and some even started up on their own. Radar would never have detected so many UFOs at the same time. These were moving at supersonic speed.
The technicians ruled out the hypothesis of meteorites, because the radars would probably not have been able to detect them.
