Malaysia Airlines Flight 370 : Ship reportedly detects “pulse” signal

534534

PERTH, Australia — A Chinese ship involved in the hunt for the missing Malaysian jetliner reported hearing a “pulse signal” Saturday in Indian Ocean waters with the same frequency emitted by the plane’s data recorders.

China‘s official Xinhua News Agency said a black box detector deployed by the ship, Haixun 01, picked up a signal at 37.5 kilohertz (cycles per second). However, Xinhua said it had not yet been determined whether the signal was related to the missing plane, citing the China Maritime Search and Rescue Center.

Malaysia’s civil aviation chief, Azharuddin Abdul Rahman, confirmed that the frequency emitted by Flight 370’s black boxes was 37.5 kilohertz.

Retired Air Chief Marshal Angus Houston, chief coordinator of the Joint Agency Coordination Center – the Australian government agency coordinating the search – said Saturday the Haixun’s report of electronic pulse signals could not be verified at this time. U.S. officials from the National Transportation Safety Board and FAA were not able to confirm the report, either.

Houston also said the report of a number of white objects on the water’s surface about 90 kilometers from the signal detection area could not be confirmed to be related to the missing plane.

The deployment of Royal Australian Air Force assets to the area where the Chinese ship detected the sounds is being considered, Houston said.

CBS News transportation safety analyst Mark Rosenker, a former chairman of the NTSB, wondered why there was no report of debris from the Chinese ship that detected the signal: “When you think about what in fact they are saying, which means they believe they have the debris site where the aircraft is laying, it defies logic that we would not be seeing something on the surface as well,” Rosenker said.

But Sky News senior correspondent Ian Woods told CBS News Radio, “The reason it is being given some credibility is because even though there are many items that could be mistaken for wreckage floating round in the ocean, there is only one thing that pulses at 37.5 kilohertz, and that is a ‘black box’ recorder.”

Rosenker also said that, if the signal came from missing plane’s flight data recorder, then it could likely take weeks or possibly longer to target and recover it.

On Thursday, the British navy’s HMS Echo reported one alert as it searched for sonic transmissions from the data recorder, but it was quickly discounted as a false alarm, the Joint Agency Coordination Center overseeing the search said. False alerts can come from animals such as whales, or interference from shipping noise.

With the batteries in the black boxes’ locator beacons due to run out any day, crews are in a desperate race against the clock.

On Friday for the first time, crews launched an underwater search trying to pick up a signal from the black box flight recorders on the Beijing-bound plane before they are expected to fall silent. The batteries last only about 30 days, which would be Monday.

The search for the Boeing 777 — plagued by confusion, and agonizing to relatives of the 239 passengers — has frustrated investigators and left many wondering how long it can go on.

Two naval ships from Australia and the United Kingdom began probing the ocean along a 150-mile route on Friday that investigators hope is close to where Malaysia Airlines Flight 370 went down. The Australian ship, Ocean Shield, is towing a U.S. Navy device that can detect signals or pings from the flight data and cockpit voice recorders, commonly known as the black boxes.

The U.S. Navy’s towed pinger locator can pick up signals to a depth of 20,000 feet, and so should be able to hear the plane’s data recorders even if they are at the deepest part of the search zone, about 19,000 feet.

But no wreckage from the plane has been found, so officials cannot even be sure they are looking in the right location. The 84,000-square-mile search area, about 1,100 miles northwest of Perth, was already shifted almost 700 miles to the north after investigators decided that the plane was traveling faster than originally thought.Plus, the pinger locator — consisting of a 30-inch cylindrical microphone attached to about 20,000 feet of cable — must be dragged slowly through the water at just 1 to 5 knots (or 1 to 6 mph) in a grid pattern.

Meanwhile, up to the 11 military planes, four civilian jets and 11 ships were to assist in Saturday’s search, led by the Australia Maritime Safety Authority. Australian officials continue to refine the area where the plane entered the water based analysis of satellite communication and the aircraft’s performance.

The Malaysia Airlines jet left Kuala Lumpur on Saturday, March 8, at 12:41 a.m. headed for Beijing. But investigators believe someone re-programmed the plane’s flight management system, and two minutes after the last conversation between air traffic controllers in Malaysia and the cockpit, the plane’s transponder was turned off. The plane went dark on civilian radar, and then made a left turn back toward Malaysia.

Sources have said it followed an established aviation corridor over several navigational “waypoints.”

The Malaysian military tracked an unidentified object now believed to have been Flight 370 on its radar traveling west towards the Strait of Malacca. At 2:15 a.m., it disappeared from the military radar, about 200 miles northwest of Penang.

Investigators say the plane’s antenna signaled to a satellite multiple times over the next several hours, with the last signal recorded at 8:11 a.m., about the time the plane would have run out of fuel.

Experts says the search in the southern Indian Ocean might have been easier had the plane been outfitted with so-called “deployable black box” technology, essentially flight recorders that eject and float when a plane crashes.

The U.S. Transportation Safety Administration tested the technology, employed on U.S. Navy jets such as the F/A-18 for more than two decades, and found that it would enhance safety on commercial aircraft. But three years after the study, no U.S. commercial airline has installed the technology. The price tag per plane is about $60,000.

As the search for the missing Malaysian jet entered its fifth week, Australian Air Chief Marshal Angus Houston, head of the joint agency coordinating the operation, has acknowledged the search area was essentially a best guess.

“They might be lucky and they might start smack bang right over the top of it,” said Geoff Dell, discipline leader of accident investigation at Central Queensland University in Australia. “But my guess is that’s not going to be the case and they’re in for a lengthy search.”

Train derailment in New York City leaves four dead, dozens injured; NTSB investigating – The Washington Post

Federal investigators are in New York to determine why a Manhattan-bound Metro-North passenger train spun out of control early Sunday in the Bronx, killing four people and propelling dozens of passengers out of their seats as Thanksgiving crowds headed home on one of the busiest travel days of the year, authorities said.

A “full team” of investigators from the National Transportation Safety Board arrived from Washington on the scene at 12:30 p.m. to find seven cars and the locomotive derailed, NTSB representative Earl Weener said in an evening news conference near the crash site — along the Harlem River and just north of the Spuyten Duyvil station — while helicopters circled above.

At least 63 people were injured, 11 of them listed in critical condition. The crash is thought to be the deadliest train wreck in New York City since 1991, when five people were killed and more than 150 were injured in a subway train derailment in Lower Manhattan, authorities said
Weener, speaking next to New York Gov. Andrew Cuomo (D), said several federal teams — including experts on tracks, signaling and breaking — would be investigating for a week to 10 days.

“Our mission is to understand not just what happened but why it happened, with the intent of preventing it from happening again,” Weener said.

In response to media questions about reports that the train conductor said the brakes had failed and that the train was being pushed by a locomotive, making it harder to stop, Weener said: “We don’t know at this point. We will be looking at it.”

Investigators will be looking at the train’s speed and had already recovered the data recorder, he said. Several passengers told the news media that the train appeared to be going too fast around the curve when it skidded off the tracks and sent some passengers flying into the air, tumbling over one another.

The Metropolitan Transportation Authority identified the victims as Donna L. Smith, 54, of Newburgh; James G. Lovell, 58, of Cold Spring; James M. Ferrari, 59, of Montrose; and Ahn Kisook, 35, of Queens. Three of them were found outside the train and one was inside, authorities said. Autopsies are scheduled for Monday.

Cuomo said the train operator was being treated for injuries and was talking with officials.

“This is an opportunity for the NTSB to review the operation,” Cuomo said. “As I said before, safety is job one. And if there is a lesson to learn, we want to make sure we learn it. It’s a reminder to all of us that life is a precious gift and take everyday as that.”

Many passengers told reporters they were sleeping or listening to music on Train 8808, which departed at 5:54 a.m. from Poughkeepsie and was due to arrive at Grand Central Terminal at 7:43 a.m.

They said they experienced a harrowing awakening after they heard screeching metal. One car flipped down a riverbank, inches from where the Harlem River meets the Hudson. New York Police Department scuba divers, along with helicopter crews and trained dogs, searched for survivors.

Many passengers were coming home from Thanksgiving weekends. Others were on their way to work, including an injured female New York City police officer in her 20s.

Fire Commissioner Salvatore J. Cassano told reporters that there were about 100 people on the train, adding that the toll would have been worse if the accident had occurred later on the busy travel day or during the workweek. “On a workday, fully occupied, it would have been a tremendous disaster,” he said

At the White House, President Obama said his “thoughts and prayers” went out to the injured and the loved ones of those killed.

This is the train service’s second passenger-train derailment in six months, during a year that has seen a string of safety problems.

The troubles for the commuter train system began May 17, when an eastbound train derailed in Bridgeport, Conn., and was hit by a westbound train in a crash that injured 73 passengers, two engineers and a conductor. Eleven days later, track foreman Robert Luden was struck and killed by a train in West Haven, Conn. It was the first time in more than four years that a Metro-North worker had been fatally struck by a train.

In an “urgent safety recommendation,” the NTSB said that a trainee rail-traffic controller had opened a section of track without the proper clearance.

This month, Metro-North’s chief engineer, Robert Puciloski, told NTSB investigators that the railroad is “behind in several areas,” including a five-year maintenance schedule, which has not been conducted in the area of the Bridgeport derailment since 2005.

“It would appear the train was clearly going too fast on the curve,” said City Council member Oliver Koppell (D-Bronx). “I take this train every morning, and they always slow on this curve. On first look, it appears the operator was going way too fast.”

Television images showed passengers emerging from the train bleeding and scratched.

Michael Keaveney, 22, a security worker who lives in a co-op apartment building overlooking the crash site, said he could not believe what he saw.

“I was dead asleep and heard a loud boom,” said Keaveney, who was reached by phone. “I could see four cars flipped over. It was shocking. My mother called 911 and I got dressed and ran down to see if I could help, but firefighters were already there.”

In July, a CSX freight train hauling trash derailed in the same area because of a track issue, but no one was injured. Keaveney said he witnessed the train flip over in that accident. “It makes me grateful that I have a car,” he said.

Joel Zaritsky of Poughkeepsie awoke early to catch the 5:54 a.m. train so he could attend a dental convention in New York. He was asleep when he was thrown to the other side of the train.

“There was smoke everywhere and debris,” he said, showing a crowd of media his bloody right hand. “I still can’t believe it. I’m very happy to be alive.”
