(this same thing happened friday, august 7th, 2020.) barely visible grey/white shape in the sky, very high altitude. first thought it a stealth military plane due to shape and our proximity to dugway proving grounds. it changed from an air force plane looking shape to a quarter moon/parachute shape. at this point i thought it was birds or bats, but the speed it was moving was much faster than any wildlife i have observed. i was in the car with my husband, we pulled over to watch it, and over the next hour witnessed upwards of 50 groups of these things. differing altitudes, some higher than the cessna were flying, some just a couple hundred feet off the ground. the closer they got, the more we could see they were not winged or one uniform object, but clusters of spheres. we called my husbands aunt who lives right up the street and met her in her front yard to make sure others were seeing it too. she also witnessed the clusters, which stopped about an hour after we saw the first one. tonight (the 11th) about 10pm i was looking in the sky in the exact same neighborhood and saw the same cluster high in the sky. my husband, his aunt, and four friends all gathered in the street and watched again as cluster after cluster flew south at unthinkable speed. there were again three cessnas flying in circles above the houses, and these were speeding/ flying past these planes with ease. again, it went on for about an hour, 50 or more sightings, and then stopped. the objects were hard to see at first, since there wasnâ€™t light or sound, but if you looked hard enough you could see a gray/white shadow looking thing flying in the sky each time. if we hadnâ€™t seen them just a hundred or so feet up, it would be plausible that they were birds or bats (that can fly 6/7 times as fast as any bird or bat iâ€™ve witnessed) but seeing close enough that they werenâ€™t in fact animals, prompted this report.
