In July 1988, a man named Carlos Manuel Mercado, residing at Betances, near the mountain range Sierra Bermeja, southwestern Puerto Rico could not sleep due to the hot weather.He was on the couch, staring at the ceiling, waiting for the night to cool down until a whitish glow from the window filled his room with bright light.
Investigating the Mercado case:
Then he heard a strange buzzing sound, followed by a knock on the window. Now, Mercado was wide awake and he walked to his window to check what it was, and what happened next changed his life.
I got up and opened the window, and there they were, 3 little fellows standing there under the window, on the sun-lounge of my house. It shook me. Because they were so different, they looked a bit like us. But they weren’t human.
In front of my house, on the other side of the road, was standing a flying saucer.
