(Undated) -- The search for a missing Malaysian airliner is the largest in aviation history and will likely be the most expensive. The month-long international effort has cost an estimated 44-million dollars since the jetliner with nearly 240 people on board disappeared. More than two-dozen countries are contributing planes, ships, submarines, and satellites to the search in the southern Indian Ocean. It's estimated the search will cost hundreds of millions of dollars by the time it's over.
