Went outside to smoke a cigarette then observered a series of 3 blinking lights that made the shape of a triangle with another light moving from one light to what appeared to be the middle of the craft and back to the light again over and over again. the triangle appeared to grow in size and retract in size a few times. i then observered 2-3 more lights to top right of the triangle then lights where whiter in color and those lights were pulsating . that’s when i ran to get the phone but i’m the excitement couldn’t remember where the kids or i left it, so i ran back out after yelling on the top of my lungs that there is a huge craft outside for anyone if they heard me. when i returned 30 seconds later the lights were still there and i observered an additional blue light moving or maybe pulsating up and down on the lower mid section of what appeared to be one giant craft or it could have been one big craft and another big on above it but they all looked connected. then i observed the craft shrink in size and descend slowly what looked to be about a mile or a few miles out but not that high. i would say it was as high as a normal helicopter flies. also after the sighting i observered many helicopters flying towards the area of the sighting also a few othe strange lights that looked off but not wired enough to call a ufo. what i saw was in fact a ufo to me and i think other worldly.
