My brother actually saw this and sent me the video however i donâ€™t think he would wanna be involved in this. he was looking at a new apartment in nyc and took a video to show. at 56 seconds into the video you can see a black dot of some sort moving at incredible speed. the object comes from the right of the big building in the center however if you slow it down enough you can see it while it is still on the left of the building come from far in the distance. i donâ€™t believe any bird or drone could move this as fast as this appears to be moving. this is 100% real and time stamped in my phone with the date and time he took it. i didnâ€™t know some of the above answers but if the information is needed i can try to find out how tall the building is he was in, etc.
