I was 12, playing in the terrace with my brother 10, we saw two light objets coming down from the sky at very high speed. They were flying over the uranium mine, at a distance of 8 kilometers from us. They came from the west, Portugal direction, stop in the sky for a while and descend to the land very quickly; the stay there for a while, like two minutes; then they lift up verticaly to the same position in sky they descend, like two kmts high. And then disapear fast in the sky in an angle of 60º. All the seeing took like 10 minutes.
