Sept. 19, 1952; Topcliffe, Yorkshire, England
10:53 a.m. [4:14 p.m.?] Operation MAINBRACE Meteor jet fighter (flown by Flight Lt. John W. Kilburn and Flight Lt. Cybulski ?) was descending to land at 5,000 ft when they saw a slow-moving circular silver [or white?] object about 5 miles behind them at about 15,000 ft following a similar course then swinging like a "falling sycamore leaf" or pendulum and began descending. As the Meteor turned towards Dishforth the object followed, then stopped falling leaf motion and descent, began rotation on its axis, suddenly accelerated at "incredible speed" faster than a meteor to the W then turned to SE [and disappeared]. Ground ? observers included Flying Officer Paris, Master Signaller Thompson, Higgins ? and 5 other aircrew [on the ground?]. (Jan Aldrich; Ruppelt pp. 195-6; 15-20 secs + ( NICAP; FUFOR Index)
