I think its now (NXI) is missing one engine in perth and basically is being 'rebuilt', 1 option is it should be ditched off fremantle its in that good of shape.
That'd be the one that has been flying around happily for over two weeks would it (apart from a breakdown caused by a dud bit from another aircraft)?
there are 4 of the newest jets in Brisbane sitting there doing nothing?
Why don't you ask the owners of the aeroplanes? There are probably good reasons why they were not given to NJS, it's just you don't know what they are.
