I don't know what's going on over the Arizona skies, but whatever it is it has made two pilots on separate planes report an unidentified flying object. A Learjet was passing through and first reported something in the air saying, "I don't know what it was. It wasn't an airplane but it was, the path was going in the opposite direction." Later, an American Airlines pilot reported something flying over top of their plane at 2,000-3,000 feet that was going in the opposite direction and had a "big reflection." It's still not known what the huge object was that flew over the two planes in Arizona. Google balloons and military aircraft have been ruled out. Have you ever thought you've seen an UFO? DO you believe there's alien life on Earth?
