With 26 nations hovering over disputed waters and fragile security zones, the search for MH370 in the southern Indian Ocean seems like a giant game of Risk.
A United Nation's agency is in charge of multi-national search and rescue operations.
But the latest drama has exposed its limits.
Some experts are urging that the rules be changed to ensure countries share accurate data and allow greater access to naval ships searching for wreckage in foreign waters.
MH370's search effort, involving ships and planes from many nations, on the surface looks likes an harmonious exercise. But behind the scenes it has been complicated by sovereignty disputes and worries about sharing sensitive military data.
At stake is the effectiveness of the 70-year-old United Nations' International Civil Aviation Organisation, which defines the protocols of air traffic investigations.
