Bruce Cathie's Auckland sighting and 'harmonic grid'
New Zealand airline pilot Bruce Cathie said he saw a UFO near Auckland in 1952, and later sightings led him to publish 'Harmonic 33' (1968), claiming that UFOs travel along a worldwide energy grid.

The account
Cathie, a National Airways Corporation pilot, mapped reported sightings onto a lattice of lines he believed encoded the speed of light and gravity in 'harmonic' numbers. His books found a lasting readership in ley-line and 'world grid' circles.
The sceptical view
The grid is numerology: with enough freedom to choose units and points, almost any set of locations can be fitted to a pattern. No physicist has found the relationships he claimed.
