I was returning home, in my car, at around 21h11min or 9:11pm, me as a passenger, when suddenly i observed in a blink of an eye one green light, flying higher as an airplane, with a speed of probably 6 to 7 times faster than any other thing i've ever seen. it flew in a straight line direction, and after cruising the sky, it vanished completly. had no time to record nothing, and the only other possible witness was not looking the same direction as i was. no sign of it, or other sigthnings after as soon as the car stoped. half hour past and no other signs of ufos.
