Anyone know more about the Valentich disappearance?

You can easily search it on the Wiki. Long story short, a guy in a small one-manned airplane was close to shore in Australia when he noticed a strange green light following him. There’s a recording of him with the airport control or whatever and it’s really unnerving as his connection fades and it ends with the screeching of metal.

Nobody ever found a plane or any kind of remnant despite him being close to shore.

That’s really about the gist of it. It’s a UFO-esque story that probably has intrigued me the most, probably because nobody knows what the hell happened nor can say where he is. It was back in the seventies I think.

One thing I’m confused about is that there was supposedly a picture taken by a bystander along the shore of a green light in the sky. I’m not sure if that was fake or before or after the incident or whatever.
