I wish the poor lass and her student a speedy recovery. Sounds like she's going to have a tough time ahead.
I was taxiing to the run up bay when it happened and didn't see it, but I was talking today to a friend who is an aircraft owner and pilot therefore reliable eyewitness, who saw and heard it all happen from the hill by the tower. No doubt what he told me will also become apparent in the ATSB report.
I hadn't been able to work out how an aircraft that "hadn't become airborne" on 24L ended up in pieces on the threshold of 30. Once he told me what he saw, it sadly made sense and of course bears no resemblance to the story the cops and media came up with.
Not going to discuss it here as I didnt witness it myself.
