I was on my balcony having a smoke, and happened to look to the North East. Thats when I say 3 objects movine across the sky towards the south. They were in a triange formation, and rotating around each other. Then a 4th appeard and they broke formation, then 2 disapeared. and there was only 2 left.I called my brother to come look, i though i was too late, i thought they were all gone..then to my suprise, they kept coming, first one at a time, then 4 at a time, then six, all together i counted 16.All of them came from the NortEastern horizion and headed south. They looked like firworks at first, when they took off from the north, strait up in the air, but then when they took off to the south, i knew at once that they were not fireworks. We thought maybe they were jets.but no sound of jet engines could be here, even at time when there were 6 in the sky at one time.I have been checking web sites all over to see if anyone else saw what i saw.There was also a single engine air plane that seem to be trying to chase the objects.
