Qld news service last night and I quote.
The owner of the aircraft (name given) didn't want the aircraft to be washed away by the incoming tide so re fuelled the aircraft and after a few anxious moments took off and made it safely to Coolangatta.
Earlier in the story it said and I quote (remember these are not my words or thoughts)
The Pilot (named) noticed that the first engine which was put in new last week began to use much more fuel than it should have then the second engine began to falter so he had about 15seconds to make the decision to land on the beach.
I saw the interview with the pilot and rightly so he said the passengers were safe and that's all that matters.
