A flight scheduled to coincide with the 30th anniversary of a sighting of a UFO over the Kaikoura coastline has been postponed until April.
Organiser Paul Davidson said not enough people had booked, so it was not viable to fly, The Marlborough Express reported.
The flight was supposed to have left on Tuesday.
A lot of people who had wanted to come could not because of the time of year, Mr Davidson said.
He hoped it would go ahead from April 11 to 13 in conjunction with the Classic Fighter Airshow at Omaka.
Thirty years ago Safe Air pilot Bill Startup saw something out the window of his Argosy freight plane that has baffled UFO sceptics and believers to this day.
Mr Startup and other crew and passengers on the original plane was due to be aboard the reconstructed flight.
The UFO - floating lights - was filmed by a professional news cameraman on board the flight.
Two separate radar systems tracked the mysterious lights off the Kaikoura Coast at the same time as the sightings and previous witnesses had also reported strange lights in the area.
Various theories have been put forward to explain the lights including atmospheric disturbance and distorted lights from the ground, but those aboard have no doubt what they saw.
Mr Davidson said it was the first time a UFO had been seen simultaneously by trained observers, tracked by radar and filmed by a professional cameraman.
