The non-human cost of retreving all wreckage must be huge. If you have the FDRs, some engines, the cockpit electronics, and can take pictures of the rest, will they continue to raise all the pieces at all cost?
I'm not intending to be morbid, but the press reported that two bodies were recently recovered and that DNA testing is being done. If the DNA tests are not conclusive, the press report said that no more bodies will be raised.
I can't image why the DNA would not be conclusive; how could that be possible?
