It was 6 reddish slightly flickering balls of light seemingly taking off from north london,on.At bout 8:17 when a friend and I seen them,3 lights leading the pack formed a triangle,paused for a few seconds,then slowly turned counter clockwise in unison.Soon after 2 of the 3 vanished and the others slowly flew off into the sky.I have been trying to find footage like crazy the second I came inside,anyone get a photo or anything?
