Aliens arrive on Earth to abduct a man in Puerto Rico and tell of a meteor which is on its way to destroy the Earth.
The first date of initial contract has been reported to be 1988 in Puerto Rico.
This sighting of aliens is one that I ignored since I know that many individuals have been abducted, and none of these abductees have been comprehensively identified. It is also likely that due to misunderstandings these individuals have tried to hide their experiences from all others, but this person in Puerto Rico appears to be an exception to the rule. He has reported it and managed to take photos of military jets flying in the vicinity of the UFO while it took off.
