Does Anyone Know What This Is???

Err. The first person to give an explanation as to what in God's name this is, gets 50 points. I don't know what it is. This photo was taken at sunset in Melbourne on 25th of June, 2005. It looks like something falling from the sky, burning. But what would take 5 minutes to fall, while still leaving a trail of fire behind it?? Answers please!!!!!
