The following exert is an eye witness statement. Please read into it what you will. This has been reported to mufon who I am sure are investigating:
Walking home on night of 11 jul 18 in the summerlin area. light and movement in upper peripheral vision caught my attention. i looked up to see a dark/black triangle-shaped structure traveling approximately eastward, then make an abrupt angled change to the northeast (not an arc like a terrestrial aircraft would make), travel very fast for only a second, and then vanish completely. the edges glowed in many hues (color-shifting) but were not bright like lightbulbs would be. the thing was completely silent. i’ve seen many drones, helicopters, and aircraft, and this was none of them. there were light clouds at the moment. the object was below the clouds but not close enough to illuminate them. however, it appeared to be higher than any drone i’ve seen. light aircraft including prop planes and helicopters are common in this area, but this was very different. i did not get the impression this was a toy, but it did not seem as large as a passenger jet. possibly as large as a cessna. the entire thing happened extremely fast. contact me for important information about my credibility.
