Steuart Campbell (born 1937) is a British writer and sceptic who lives in Edinburgh.

The book examines eyewitness reports, as well as photos and instrumental evidence.

[3] Campbell concluded that the alleged sightings are best explained by logs, otters, ripples, seiches, wakes and hoaxes.

[4][5][6][7] In 1994 Campbell's book The UFO Mystery Solved was published by Explicit.

The work was reviewed in the Journal of Meteorology as "a well-researched book" that will assist in dispelling the mysteries surrounding unidentified flying objects.
