2 small, cylindrical shaped ufo's in sky over Barcelona.I first noticed one shiny object reflected by the sun, cylindrical but bulged at each end. It appeared to be at around 12,000 ft, and was quite small - like a small aircraft. It was travelling towards me at a faster than small aircraft speed. After a few seconds it suddenly disappeared. After about 1 minute, another identical vehicle appeared in near the same place, it hovered, moved sharply right, hovered, moved back left, dipped a bit - then , poof it disappeared.
