I was sitting in my seat at the MCG for the Grand Final. There was no mention of the A330 fly past. The A330 came over low, loud and fast. The all white jet (from below) came and went in a matter of seconds. I only saw it for a split second after I heard the noise and looked up. People around me had no idea what airline they had seen. Most sighed in relief when it was gone. Their initial, instant reaction was it was an aircraft on a terrorist attack!
