I was watering and weeding in the backyard. I saw a roundish silver shaped object moving north toward the city at a slow straight pace just under the lower cloud deck to the east of my home 5-6pm Friday September 13 in Brookside… a Kansas City suburb…leaving a long entrail behind it. Beautiful sun filled day…The sun reflected off the metal at one point …. No sound … no propellers or wings. Possible drone or military craft…. But very odd. A helicopter was present first and drew my attention which made me look up and see the entrail and then the object… gone from eyesight about a minute or less after view… entrail was all remaining
