Commentary on the sustainability of this item: “Qantas (QF) and SkyNRG will operate Australia’s first commercial biofuel flight April 13 between Sydney and Adelaide. The flight, using an Airbus A330, will operate using a 50:50 blend of biofuel derived from used cooking oil and conventional jet fuel, QF said in a statement.”
Hmmm… a sustainable fuel resource? The only way to keep QANTAS flying this way is for everybody in Australia to eat ONLY lots of deep-fried food. Consider half of the 139,000 litres of the A330′s fuel capacity will be deep-fried product. Consuming up to seventy-thousand litres (approx 18,500 US gallons) of used cooking oil per flight.
Airport staff will no doubt be issued with guns loaded with bird-shot to maintain a safe air space for other aircraft following QF1121 and QF1120; from seagulls looking for free chips. Baggage handlers to be issued with bio-hazard gear so that the droppings of 100,00 gulls don’t give them bird-flu.
At least the chip-shops under the flight path will get a run of salivating customers.
The flights are on Friday the 13th. So all the stars are aligned.
Joycey; are you sure you want to humour the nitwits with such a useless, unsustainable exercise?
Why not drop into Contrary2Belief and browse around, see what other little gems they have. h/t Bernd Felsche, with a nod for creative self-promotion 
I think I’ll watch this maiden flight from the ground! (Can you say “maiden” flight anymore in this PC era?)
Global consumption of vegetable oils is about 176 million tonnes/year.
Global consumption of jet fuel is about 2 billion barrels/year.
Even 100% recovery of used cooking oils isn’t going to do the job.
