UFO Sighting in Billings, Montana on 2017-06-02 13:30:00 - I saw the object after playing noon ball. it rotated around its axis as it moved.
After playing noon basketball in billings montana (1:30 pm), a reflection caught my attention in the sky. the object was in the general direction of the airport and high in the sky 60 to 70 degrees. at first i thought it might be a group of bright metallic balloons filled with helium, but the object was rotating in a regular manner with asymmetrical protrusions appearing in a cyclic manner. this made it unlikely that the object was a drone in my opinion. it was also not an airplane or a helicopter - and because of the bright shiny reflections not a bird or other object i could think of.
