2 huge crafts flew over us, then stopped 500 meters away, then took of vertically with high speed. They were as large as oil tankers.We saw 2 huge triangular crafts, more then 300 feet wide fly over us, 3 persons that where coming home saw it. It flew over our house to the other side.We all start running to the other side of the house to see more. There we saw the 2 crafts coming to a hold. After hovering for a few seconds they took off vertically.The whole time there was no sound. The craft had 3 white circular lights at the bottom and a red light in the middle. The craft were very large.The only size to compare we could think of was an oil tanker.This all took place about 100 meters from the beach of the Mediterranean Sea of the coast of southeast Spain in a town called Daimus.
