Fuel and wreckage
Your very detailed website calculations on fuel usage show what was possible ( from some of the questions on here I wonder if people have read it! ). I must admit to initially doubting the range issue but
having gone through it all I'm beginning to think you might have something. In all your research have you heard anything about whether a Japanese patrol might have earlier stumbled on the wreckage ,
just like the Australian patrol did , and maybe removed any wreck contents they might have passed on to their intelligence people?
