Bruce Cathie

Bruce Leonard Cathie (11 February 1930 – 2 June 2013) was a New Zealand airline captain, author, and self-styled ufologist best known for developing a theory that sought to explain the flight paths of unidentified flying objects (UFOs). Trained as an engineer and later serving with the Royal New Zealand Air Force, he flew for the New Zealand National Airways Corporation from the 1950s onward. He became prominent after a widely publicised 1952 sighting over Manukau Harbour. Cathie went on to publish six books between 1968 and 1994, addressing subjects such as harmonic mathematics, anti-gravity, and nuclear testing. His work was circulated in New Zealand, the United Kingdom, and the United States, where it attracted both scepticism and support.
