U.S. Air Force Analysis of Flying Objects in the United States, 1-100

Capt Ryherd saw two unidentified aerial objects at approximately 8,000 to 10,000 ft traveling above a P-80. He thought they were approximately 15 to 25 feet in diameter. In shape they were circular like a ball on the bottom but not completely round. The first flew straight and level but the second flying close behind the first at the same altitude seemed to be going from left to right and right to left — more like a guard in an aircraft formation. Due to the noise of the P-80, no sound could be heard from them. They did not leave any vapor smoke or visible trail. The weather was clear and Captain Ryher and Lt Ward Stewart watched them until they disappeared in flight — presumably over Oakland headed toward the ocean. NOTE: Capt Ryherd showed extreme sincerity throughout the interview
