At 11:50 am on june 17 2021 i seen a jet aircraft flying at around 30’000 ft . About a minute later i seen a black circle object flying at an altitude even highr then the airplane following it in the same direction , i yelled to my wife to come look at this out the window she seen it also . It had to be around 50,000 ft in the air . The object was black with what looked to be a whiteish circle around it . I will email you photos , as i am still in shock as to what i seen . The skies were perfectly clear . But still was hard to see. I had to zoom in the camera to see it good .
