I was going out with my family, and we were in the beach, walking, then i looked to the sea, and a light just apper from nowhere and go left to right and then disapear, another do the same after the first one disapear, but above the first, a third came at the same place the first appered, and the last on, on the place of the second,but the last don disapear like the others, it started to go up and go behind a mountain.My first thinking is: a normal ship using some kind of fireworks, but there was no ship, and in S���o Vicente is a passage of ships, and you can still seeing them(the ships) at any time of the day, then i though, it was airplanes or helicopters, but it was to fast and airplanes dont appears from nowhere and disapear.I don't know what i felt, think I was happy and surprise(my first ufo view =D)
