After work i was headed home and i noticed a plane in the sky that i thought was a b-2 bomber (turns out it was a cessna-172) so i took a few pictures of it. when i took my phone out to take the pictures i zoomed in on the aircraft and noticed a strange white/silver orb that was performing incredible maneuvers around the plane in center frame. it flew very quickly in an erratic fashion around the plane and seemed to making sharp turns seemingly unaffected by its own velocity or gravity, it also hovered for a bit behind the plane before vanishing toward the east. having worked around aircraft of all kinds for sometime i can definitively say this craft was exotic looking with no markings, no rudders, no visible engines or exhaust plume. it also seemed to reflect sunlight in a strange way that haven't seen before as if its surface material was a mirror.
