Time, but not hope, is quickly running out

Will this week produce the breakthrough the world has been waiting for in the search for Malaysia Airlines flight MH370?

For the men and women from the many countries who have been scouring vast stretches of the Indian Ocean from the air, and for those at sea, they live in hope.

Hope that the next piece of debris hauled from the ocean belongs to the Boeing 777 that disappeared on March 9, on what was to be a six-hour flight from Kuala Lumpur to Beijing, with the loss of all 239 passengers - most of whom were from China - and crew.
