A prominent UFO sighting in Central Hawke's Bay half a century ago remains a mystery despite what became common acceptance of its authenticity.
The sighting, at "close quarters", was made 50 years ago on a Wednesday by security officer John Cudby during his rounds at the Waipukurau Aerodrome.
Following up suspicions a loose dog was on the grounds and concerns about sheep that appeared to have been herded into the corner of a paddock, the now-late Cudby had, on later reflection, had his awareness of something less natural aroused when he heard a "humming" similar to that of a vacuum cleaner.
With his own dog growling and spotting unusual reflections in the windows of a hangar, he turned to see three lights — two green separated by a red light — coming from something that appeared to be hovering about 20m above the ground. The humming appeared to be also coming from the "large object" in the air.
Cudby ran to his vehicle, and grabbed a light which he managed to play on to the object, as the humming increased to a louder whining and he became aware of the size of the suspended object he estimated to be at least 20m across.
