Yesterday at around 5pm in Western Australia, a light plane crashed into the Swan River in front of hundreds of Australia Day revellers. The Grumman G-73 Mallard flying boat was said to be exhibiting unstable behaviour in the sky, with multiple videos being uploaded to social media immediately after the crash as revellers had filmed the plane flying erratically.
