With the words ‘hope’, ‘lost’ and ‘search’ now qualifying almost every report on the Missing Malaysia Airlines flight MH370, 23 days, after it disappeared, experts are of the view that the focus should shift to finding the black box.

The device’s batteries are said to be able to last for 30 days before it stops emitting locator pings.

This increasingly seems to put a fait accompli deadline on the search efforts on-going now.

Also, the search is likely to move from the surface of the Indian Ocean, an area the size of Poland according to some reports, to underneath the water.

The underwater search will be hinged on hi-tech, state of the art US Navy equipment.

A Bluefin-21 autonomous submarine that can dive to 14,763 feet and the Towed Pinger Locator or TPL-25, a 29kg system that can detect the telltale ping of a black box to a depth of 20,000 feet.

Three deep-sea "Abyss" type submarines used to search for wreckage of the crashed Air France Flight 447 have also been sent to aid in the search for MH370.

CSI, air crash scene

According to a report in Wired, an aircraft crash reconstruction is like the world’s most complicated jigsaw puzzle Forensic pathologists, odontologists, anthropologists, and fingerprint experts will be on hand should any debris show up, but the focus of the search is quite clearly now the black box.

The colour orange

The colour orange has already popped up in some debris spotted and is important because the black box, is actually orange.
