Physician Cromwell Mortimer reported seeing the spacecraft over Central London back in 1742, when George II was on the throne.
Mortimer, secretary of the Royal Society, saw the UFO above St James's Park as he was walking towards Westminster on December 16 at 8.40 pm and drew a diagram of the mystery object.
The scientist wrote: "I saw a light arise from behind the trees and houses in the south by west point. When it had risen to the height of about 20 degrees, it took a motion nearly parallel to the horizon and went over the houses."
Mortimer added: "Its motion was so very slow, that I had above half a minute in view; and had time enough to contemplate its appearance fully."
