My family and I were flying from St. Peters FL to Winnipeg MB. We had been in the air for about 1.5hrs. I looked out my window on the right side of the plane when i saw what looked like a smaller plane with no paint on it about 1000 feet below us. I watched and looked close at it and saw that it looked more like a diamond shape. it was moving away from the plane then slowed down and it shot in the other direction to fast for it to bee a plane and i lost track of it right away.There was only 1 object that I saw. It was a diamond shape and silver. There were large clouds around it but none of them blocked my view any time during the sighting. I never told anyone on the plane that there was something out there to avoid embaressement. I'm uniware of anyone else witnessing the object besides me. If there were any electrical or magnetic effects to the plane, the pilots would be the only ones to know.((NUFORC Note: We have estimated the location of the aircraft, based on the description by the witness.
