Another late 1940s sighting (1948) this one was near Cave Creek, Arizona. A retired Commercial Airlines Pilot was flying his privately owned aircraft around Midnight. Suddenly he saw what he described as a Giant Flying Wing (with an estimated travel speed of 300 miles per hour) fly past him and stop in mid-air. Motionless for a few seconds, the Object flew straight up to possibly 10,000 feet at a fantastic rate of climb (speed). Somewhat nervous, the Pilot maintained his course and did not investigate further. He reported his encounter to the proper Authorities.
