The three-week hunt for Malaysia Airlines flight 370 has turned up no confirmed sign of the Boeing 777, which disappeared March 8 with 239 people on board, bound for Beijing from Kuala Lumpur.

The search and investigation are now focused on the Indian Ocean. The U.S. Navy is involved, and has sent equipment from a Boston-area robotics company to help in the efforts. From the Here & Now Contributors Network, Gabrielle Emanuel of WBUR reports.
