I would have to agree that to spend money on searching for MIA that have little chance of being found is a waste of money.
HOWEVER, when there is a chance of finding a MIA or something of historical significance is important then money should be spent. The most recent examples of these are the Sydney, the recent Vietnam recoveries and when infomation has come to light of burials in France. There are other examples.
My greatest disappointment is that during my 30 years in the Navy there was always a lot of talk at senior levels (at all levels) about searching for the three major missing wrecks of historical significance to the Navy ie Sydney in the Indian Ocean, the submarine AE1 of New Guinea and AE2 in the Dardinelles but nothing was never done - realistically the Navy could have found the Sydney from anytime after about 1980 if it wanted - thats when the technology made it possible.
It is only in the past few years that AE2 was found - when what were junior officers all those years ago became senior or retired.
I think these seaches are important - they are worth more to the psychic of the country than the costs would reflect.
Wikipedia have already updated their sites and are well worth having a look at - the first link is about the Kormoran and the second is about the battle - well worth reading.
