Malaysia Jet Probe Taps Black-Box Data in Hunt for Rocket Traces | Bloomberg

Data from the downed Malaysian jet’s black boxes has been successfully downloaded a week after the tragedy in east Ukraine, with the examination of bodies also under way as crash experts seek evidence of a missile strike.

The U.K. Air Accidents Investigation Branch gained access to the Boeing Co. 777’s flight-data readings today after yesterday retrieving cockpit-voice recordings, according to Dutch authorities who are leading the probe in recognition of the fact that almost 200 victims were from the Netherlands.

Specialists from the Dutch National Forensic Investigation Team are working in Kharkiv in government-controlled Ukraine after some of the 298 dead were moved there by train, with bodies being flown on to the Netherlands. While the flight recorders may reveal evidence of a missile attack, the fragmentation warhead thought to have been used will have peppered the 777’s fuselage and potentially its occupants, leaving the probe less dependent on an examination of a crash site that’s been heavily disturbed since the July 17 incident.

Radio signals that may have been emanating from the flight recorder of Malaysian Airlines Flight 370 marked the beginning of a new phase of the search for the aircraft and its passengers. Once signals emerged, the investigation expanded to include exploration of the ocean floor to detect the aircraft and recover the block box.

The location of the black box is estimated to be about 15,000 feet (4.6 kilometers) below the ocean surface. The pressure at such depths in the ocean is about 455 times the atmospheric pressure at sea level. The remains of Titanic are located at a depth of 12,500 feet (3.8 kilometers) depth, which has pressure of about 380 atm. The additional 2,500 feet increases the pressure by 75 atm. In addition, the temperature is only 34 to 40 degrees Fahrenheit (1 to 4 degrees Celsius) at such depths.
