The UFO flew down the valley below the block of flats from which I and my friends witnessed it. At first it appeared as a triangular formation of bright greenish lights, each emmiting a trai. The trees and lights below it were clearly visible, as if the craft was transparent or it was a formation of tiny craft flying together. It made no sound, and moved slowly down the valley, then rose, shrank into a single light, and shot away at incredible speed, vanishing in seconds.My mother, sister and her boyfriend saw it first, and called me. It was a triangular shaped cluster of lights, like an invisible delta winged aircraft with lights along the edges of its wings, nose and tail. The lights were bright, greenish and teardrop shaped, like flames. It moved very slowly down the valley below us, making no sound. As it moved away it gathered speed and shrank to a single light, then shot away at incredible speed. That same night, it was sighted in several other places over Mahe and the surrounding sea, each time described differently. Over the airport, witnesses described it as a disc shaped craft with lights all around it, the tracking station described it as a cylinder of lights, and it was seen out at sea as a sphere of lights hovering over the ocean. This was all reported in the local newspaper the following day, complete with illustrations. These sightings were made within minutes of each other, and all the witnesses agreed that it made no sound.
