MH370 search: Most expensive in aviation history

SYDNEY (Reuters) - The hunt for missing Malaysian Airlines Flight MH370 is on track to cost hundreds of millions of dollars, becoming the most expensive search in aviation history with 26 countries contributing planes, ships, submarines and satellites to the international effort.

A month into the search for the jet, estimates compiled by Reuters show that at least $44 million (26 million pounds) has already been spent on the deployment of military ships and aircraft in the Indian Ocean and South China Sea by Australia, China, the United States and Vietnam. The figure is based on defence force statistics on available hourly costs of various assets, estimates by defence analysts and costs reported by the Pentagon.
