Apparently, the New Zealand Air Force just released a bunch of documents pertaining to UFO investigations over the past 50  years.
They include a well-known sighting from 1978 in which a cargo plane said it was being followed by strange lights - and was backed up by radar images from air traffic controllers. However, an Air Force report at the time explained it away as lights from Japanese squid boats reflecting off clouds.
If you ask kiwi UFO aficionado Jeff Stone, this explanation is completely bogus.
"A squid boat doing 700 miles an hour and turned up on radar?"
But if you ask kiwi rugby referee and butcher Alan Hickey, he knew it was squid boats all along.
"It made me laugh [when it was reported]. I thought, ah, it's those squid boats."
What were they fishing for? Probably Nototodarus gouldi or Nototodarus sloanii, both members of the frequently-fished family Ommastrephidae (the same family as Humboldt squid).
