Bruce Leonard Cathie (11 February 1930 – 2 June 2013) was a New Zealand airline pilot who wrote seven books related to flying saucers and a "World energy grid".
His central thesis was that he could use mathematics to describe a grid-like pattern on Earth (i.e. the Electro-dynamic field on Earth) that powers flying saucers and controls the dates and places where nuclear bombs can function; in his book "The Harmonic Conquest of Space".
Cathie said that he first saw a flying saucer over the Manukau Harbour, Auckland in 1952 and in discussions with other airline pilots discovered this was not uncommon.
[3] New Zealand millennial author Barry Smith claimed to have received his information on restrictions on nuclear weapons from Cathie.
In co-operation with mathematician Rod Maupin they developed software (Gridpoint Atlas) that would plot the proposed grid-lines on Google Earth.
