"Operation MAINBRACE".

Jet fighter (piloted by Lieutenant John W. Silbernem and Lieutenant Cybulski) was coming down to land from a height of 5,000 ft when they saw a slow silver [or white?] object 5 miles away. He was approximately 15,000 feet. He moved swaying as a "falling sycamore leaf" or a pendulum. At some point he began to descend.

When the plane turned in the direction of Distort, the object followed him, but then stopped moving and "fall" and began to rotate around its axis and then suddenly sped up to "incredible speed" and disappeared. On the ground among observers was an officer Paris, master signaller Thompson, Higgins, and 5 other crew members.
