Bright flashing light moving great distance in under a second in south NJ.I was at a friend's house sitting on his front porch busy street busy area. Talking about random stuff video games, etc.. He was like hey look at that, I'm like what ... look right there he pointed out a weird flashing object kind of strobish and similar to a plane flash but much brighter. I said that's a plane he said no look how it's moving. From where we were sitting he had a telephone pole to our right on an angle so we eyed it up with the pole to see which way it's moving if it even is moving and sure enough a couple of seconds after we did that it started moving.In between the bright flashes, within a mili second of each one, we saw it in one spot then wam it was at least 1,000 yards (from our eyes, could be miles in the sky) but away from its original position. We had a hard time keeping up with it in between flashes and moving irradic from left to right up And down. Nothing that a plane helicopter or drone in today's world that's known to the public can move with such speed and agility. Literally between its flashes, which was absolutely in under a second, it was in a totally different spot far away from the last position. We watched do this for at least 15-20 minutes moving around. Then it started moving a little farther away from us south east direction but still very visible with the flashes so bright. But now it would flash then go dark completely no lights and show up in a totally different spot then it was like before. We knew by then it wasn't a normal plane especially because there are a bunch of planes flying in the sky and you see their regular flashes .So we were asking ourselves how do these planes not see see this and move out the way or change course, but the way this thing was moving, it couldn't be near them at the speed in which it moved. Then, after a minute or so of it going dark, a flashing, then dark again, moving to different spots. It started flashing and rising up and just hovered while flashing. Then lit up solid blue or white kind of like a floodlight, but nothing projecting down like you see with other common flood lights or search lights on commercial equipment, it just lit up whatever this thing was. And for the way it reflected off the object it had to be a light colored object (white light with grey object projects a blueish color).It was fully lit up for about a good 25 seconds went completely dark again then within a mili second we saw the flash of it farther away from where it was lit up which is farther away from where we were. So more south central south east . The only thing out that way that it could be as high as it was a project that bright of a light is fort dix combined base no other airports or private places for such a thing in that direction then fort dix joint base. And in that direction depending on which part of the base is a given 30 to 80 miles away from us. So that thing was bright .After it headed farther away and disappeared me and my friend went to go get food took about 10 minutes or a little over got back to his house sat on the porch ate an we were still talking about it we never seen anything like it definitely unexplainable when all of sudden we saw it again back in the same area where it was before moving all over and flashing but did not light up solid or hover. Just kept flashing then went dark and it was gone. We sat outside for another 20 minutes looking at the sky, never saw it again or anything like it, just saw your normal plane passing by .It was truly amazing how it moved liked that in a blink of an eye. A night to remember never saw anything like this here before hopefully someone else saw this too and didn't blow it off as a plane it was anything, but I know the area very well and seen everything from regular helicopters to police helis, blackhawks An your military crafts fly by all the time with lights on and off day and night just as common as your regular plane and you can hear these far away aswell as a very lit up landscape from homes ect so to be that bright to outshine everything else wow . . This thing had no sound and moved like no other craft known to the public could truly remarkable experience I will never forget.((NUFORC Note: Source of the report elects to remain anonymous; provides no contact information.
