USAF First Lieutenant Charles Scharf, pilot of F-102 jet fighter (no. 1425) with 318th FI Sq. McChord AFB, Tacoma, Wash, and ground witnesses (?) saw a pinkish-whitish cylindrical object (length/width ratio 12:1) with a slight orange tint (?) and a dark circle in the center approaching at high speed at about 30° elevation with an oscillating motion. F-102 was heading S or 180° between 40,000 and 50,000 feet at about 600 mph. Pilot banked left to keep object in sight, object continued N, then climbed, decelerated, made a large 360° orbit, then circled the jet three times as it descended closer. Object finally pitched up 45° and accelerated in a climb, rapidly disappearing on a NW heading.
