Large U.f.o

I went out for a walk outside,I was looking up at the sky,I had a sense to & when I looked up the sky was very cloudy but I could see the sky clear a bit and spotted 3 lights high up in the sky,it came closer & closer & was just hoovering in the sky,it looked like a black triangle and it had a light on each corner,I kept staring then I saw 3 small lights drop out of it in a trail,then all of a sudden it just disapeared,I never got to record it,I did try,crap camera..
