Are there UFOs above Parliament House? Strange aircraft captured streaking across the sky in Canberra

Footage showing a strange object streaking across the sky beneath a jet plane has emerged, prompting questions about what the other aircraft could be.

Filmed a few years ago but released this week, the video – which was uploaded to YouTube – shows the view outside the left side of a carrier aircraft with the wing in sight.

Posted by Finding UFO, a group whose aim is to spot unidentified flying objects across Australia, the footage shows a small white disc zooming across the sky in the blink of an eye through the airspace above Canberra.

'The UFO was flying very fast below the Aircraft. It doesn't look like a normal plane or helicopter but it looks like a flying saucer.'
