Duncan Lunan was a Scottish writer of popular science and science fiction who, in his 1974 book Man and the Stars,¹ argued cogently that certain historical radio anomalies^{2, 3, 4} could best be accounted for in terms of long-delay echoes from a Bracewell probe located at one of the Earth-Moon Lagrangian points. The anomalies he referred to were subsequently explained in more mundane terms.⁵
