Flight MH370: families’ anger eruptsComment on this story
Kuala Lampur - Chinese relatives' anger over sparse information on the fate of their loved ones on board a missing Malaysian airliner sparked chaotic scenes on Wednesday at the headquarters of a search operation that has so far turned up few clues.
Malaysia's transport minister ordered an inquiry after security guards carried out the distraught mother of a passenger on Malaysia Airlines Flight MH370 from a briefing room where she had protested about a lack of transparency, 12 days after the plane vanished.
“They are just saying wait for information. Wait for information. We don't know how long we have to wait,” cried the woman before being whisked away from a massive media scrum.
Minister Hishammuddin Hussein said he regretted the anguish.
“Malaysia is doing everything in its power to find MH370 and hopefully bring some degree of closure for those whose family members are missing,” he said in a statement.
Prospects that a 26-nation operation would lead to quick results appeared to be dwindling, however, as investigators confirmed they were focusing on the remote southern Indian Ocean after failing to find any traces of the jet further north.
“Our top priority is being given to that area,” Hishammuddin told the news conference, confirming an earlier Reuters report.
No wreckage has been found from Flight MH370, which vanished from air traffic control screens off Malaysia's east coast at 1:21 a.m. local time on March 8 (1721 GMT March 7), less than an hour after taking off from Kuala Lumpur bound for Beijing.
An unprecedented search for the Boeing 777-200ER is under way in two vast search corridors: one arcing north overland from Laos towards the Caspian Sea, the other curving south across the Indian Ocean from west of Indonesia's Sumatra island to west of Australia.
“The working assumption is that it went south, and furthermore that it went to the southern end of that corridor,” said a source close to the investigation.
The view is based on the lack of any evidence from countries along the northern corridor that the plane entered their airspace, and the failure to find any trace of wreckage in searches in the upper part of the southern corridor.
Some sources involved in the investigation have voiced fears it could stall due to the reluctance of countries in the region to share militarily sensitive radar data that might shed new light on the direction the jet took.
Two people familiar with the investigation said the search had been hampered in some cases by delays over the paperwork needed to allow foreign maritime surveillance aircraft into territorial waters without a formal diplomatic request.
“These are basically spy planes; that's what they were designed for,” said one source close to the investigation, explaining the hesitance of some nations to give blanket permission for other countries to scour their waters.
Hishammuddin confirmed that some assets that could be involved in the search were waiting for diplomatic clearance.
“The search for MH370 involves diplomatic, technical and logistical challenges,” he told the news conference, held in a Kuala Lumpur airport hotel that has served as a temporary crisis coordination centre and a base for dozens of news organizations.
Malaysian and US officials believe the aircraft was deliberately diverted perhaps thousands of miles off course, but an exhaustive background search of the passengers and crew aboard has not yielded anything that might explain why.
If it did indeed end up in the southern Indian Ocean, one of the remotest places on Earth and also one of the deepest seas, it increases the chance it may never be found - and investigators may never know for sure what happened on board.
Officials believe that someone with detailed knowledge of both the Boeing 777 and commercial aviation navigation switched off two vital datalinks: the ACARS system, which relays maintenance data back to the ground, and the transponder, which enables the plane to be seen by civilian radar.
Police have searched the homes of pilot Zaharie Ahmad Shah, 53, and co-pilot Fariq Abdul Hamid, 27. Among the items taken were a flight simulator Zaharie had built in his home.
Malaysia's police chief, Khalid Abu Bakar, said an examination of the flight simulator showed its data log had been cleared on Feb. 3. “The experts are looking at what are the logs that have been cleared,” he told the news conference.
Malaysian authorities have given the FBI access to electronic data generated by both pilots, including data from a hard drive attached to the captain's flight simulator and from electronic media used by the co-pilot, a US law enforcement official told Reuters.
The official said he could not confirm that some data had been wiped from the simulator and stressed that there was no guarantee the FBI analysis would turn up any fresh clues.
Investigators piecing together patchy data from military radar and satellites believe that minutes later the plane turned sharply west, re-crossing the Malay Peninsula and following an established commercial route towards India.
After that, ephemeral pings picked up by one commercial satellite suggest the aircraft flew on for at least six hours.
Australia is leading the search of the southern part of the southern corridor, with assistance from the US Navy.
It has shrunk its search field based on satellite tracking data and analysis of weather and currents, but it still covers an area of 600 000 sq km (230 000 sq miles), roughly the size of Spain and Portugal.
