There's a rumour getting around that the aircraft may have run out of fuel...
If it did, I would not be surprised. The fuel gauge's in the J160 Jabiru are a shocker and only work when the aircraft is stationary, if at all. Rather than use them from the bottom up, ie, if it's empty add 50 litres, you need to go from the top down; ie. have it full when you start, then count backwards for your endurance. I hope that makes sense. Once it's below half there's no guarantee that you know how much is in there.
