Search has resumed for missing Malaysia Airlines Flight 370

Australia has already spent millions of dollars on search, David Soucie notes

MH370 search set to be most expensive in history, Soucie says

But the cost of not finding out what happened even greater, he says

(CNN) —  

I know from experience how the lack of tangible evidence gnaws at an accident investigator. Eventually, the passion driving efforts to find answers is replaced with a feeling of futility and hopelessness. For the investigator in charge, valuable time that could be spent on the search and investigation will be spent justifying the cost of the search to the bureaucracy. But as the search for Malaysia Airlines Flight 370 resumes after a four-month hiatus, investigators must realize the question here is not how much it will cost to find the airplane and determine the cause to ensure it won’t happen again. Instead, the question should be this: How much will it cost if they don’t?

Armed with new maps of the seafloor from an extensive survey operation funded by the Australian Transportation Safety Board, the Fugro Equator has resumed the underwater search for MH370. Three ships will begin searching for debris on the ocean floor in a refined search area after new information revealing an attempt to communicate with the plane via satellite phone prompted investigators to revise the search area much farther south than previously.

Each of the search vessels has been fitted with sophisticated underwater sonar equipment designed to use a towed device to examine the bottom of the ocean floor for abnormalities that may be remnants of the Boeing 777 that vanished from radar on March 8. The Echo Surveyor II being used is much more capable, and can work at more extreme depths, than the Bluefin 21 used in previous searches.

But all this sophisticated equipment and trained scientists to operate it is not cheap. Australian Deputy Prime Minister Warren Truss announced a $50 million (Australian dollars) contract in August to fund yet another round of searches for the missing plane and 239 passengers and crew, while Australian Air Chief Marshal Angus Houston reportedly estimated as much as $25 million has been paid to the defense force for the visual search it conducted. In addition, another $60 million has been committed for the underwater search. Finally, if and when the aircraft is found, the retrieval and causal investigation could easily add $50 million or more to the price tag.

All this adds up to what would be the costliest search in history, more even than the
