"It tilted towards me and shot up into the sky at an angle," he wrote in a report reproduced in later UFO research.
"The windsock on top of the hangar started rotating very fast and squeaking, and I was distracted by this, but suddenly the sock stood straight out from the pole and then dropped, as if cut with a knife."
Cudby said he ran behind the hangar, but the object had vanished. He then measured 19 paces where the air above the ground appeared warm, immediately below where he estimated the object had been hovering. The grass on one hand was warm, on the other it was wet.
He then headed for the police station to report the incident, assessing the object had headed in the direction of Pukeora to the southwest of the town, in the direction where two farming families reported they had heard what they thought was a jet passing over, or even closer, in trouble and looking for somewhere to land.
A farmer apparently not linked to the two who'd heard the jet-sounding noise was to reveal his sheep had been unusually disturbed about the same time. And a visitor to Hawke's Bay driving State Highway 2 over Pukeora Hill towards Waipukurau and overlooking the aerodrome in the distance reported what appeared to be a "dark" object over the area, on what was clear early-morning conditions with a starry sky.
"I had often read about UFOs, and always sceptical about them," the visitor said.
"Then I realised with a kind of sick shock that I was looking at one. The object appeared to be circular, and was stationary about 100 feet above the ground when I first saw it. Then it gradually gained height, and abruptly took off southwards."
The report said that neither Cudby nor the traveller, a Mr Grant, knew that either had separately reported what they had seen.
Cudby's son, Mike, remains in Waipukurau and said this week he remembered overhearing the subject being talked about by his father.
Another from the area recalled there was some scepticism about the accuracy of what witnesses had seen, but added: "At the end, I think it seemed there was something in it."
