About 6:05pm,i was sitting & reading outside my apt..It was clear, but a few clouds to the south. i observed that a 2 seater plane was going over my head. i looked up, and i thought it was towing something like a banner. the ufo was right above the right wing. i watched it. when it got just past the i-74, the ufo made an immediate right turn. it flew so fast. and then it hovered.The airplane went on to the southeast. the ufo changed & went left for a few miles. then it hovered. it went up very slowly. all of the sudden it went very fast into the clouds. afterwards, i saw a helicoptor at 6:20pm going in the same direction. it was black, also. the ufo was black & rectangler shaped from the bottom. then i saw it a few miles away-it was still black & indentured at the top. my printer isnt working.
