it was a bright cloudless day. i was on my back porch. we are located 7 miles inland from lake ontario n.Y. point of interest..There are 3 nuclear power plants on this shore. i heard a jet airliner passing over head. as i am always looking for/at "chemtrails" i looked up to find the plane. the sky was clear, but for an airliner flying in the direction of ottowa canada. the airliner was not emmiting any contrail. as i watched, two bright silver orbs approached from the left. they were one behind the other with one(rear) to the left of the other. they passed under the airliner's tail. crossing at an angle. i believe that they weren't very close to the plane.Ex. the airliner could be "covered by a quarter" the orbs were closer to a half dollar. the rear orb moved to the front of the front orb (left side) then crossed in front of it to the right side. then "slowed down" and crossed behind, back towards it's original position. i lost sight as they had moved from my range of vision. this happened very rapidly. the sun was "high in the sky" and to my rear left (11 o'clock). no birds, just clear blue sky. the orbs weren't following the airliner.
