57. Missing Malaysia airplane

The search1 for a Malaysia Airlines passenger jet 2 expanded this week.  The airplane, a Boeing 777, disappeared3 last Saturday on a flight4 from Kuala Lumpur to Beijing.  It was carrying5 239 people. 

At first6, the search was along7 its expected flight path8.  But by week’s end, crews9 had expanded the search across10 parts of southern Asia for any evidence of Malaysian Airlines Flight 370.                          
With satellites and other technology available11, how can12 a plane as large as the “Triple-7” just13 disappear?  Air safety expert14 John McGraw says it is easier than you may think15.
“People are under16 the impression that every airplane, even when17 it’s flying across the ocean, is observed on some kind of18 radar scope, with a human being19 looking at that scope.  And it's just not the case.  Radars don't reach20 that far21.”

But John McGraw says there are also22 a lot of devices23 inside the Triple-7 that can help searchers24 follow25 its movement.

Systems in the aircraft send26 altitude, weather conditions27, position and speed to air traffic controllers28.  There are also at least29 three ways the pilots can communicate with controllers.  Another tool30 is the flight data recorder31 or “black box.”  If the plane is downed32 in the ocean, the black box sends out a signal33 that can travel up to34 three kilometers away35.                                          4
Many people remember when a French passenger jet disappeared five years ago.  Air France Flight 447 went missing36 as it flew37 from Brazil to Paris.  Its wreckage38 was eventually found39 in the Atlantic Ocean.
Air safety expert John McGraw remembers the National Transportation Safety Board40 taking action after the French jet went missing.  He says US officials called for continuous download of an aircraft’s flight data recorder information in case of emergencies

“In the past they haven’t been able to justify41 installing that kind of equipment, because it’s expensive42, and because there hadn’t been43 that many accidents where it would have come into play44.  This will certainly provide some additional motivation and there may be calls to do that.”
Malaysia Airlines Flight 370 was last seen45 on radar above46 Vietnam and Malaysia.  Air traffic controllers in both47 countries say they did not receive48 any message that the plane may have been in trouble49.  On Tuesday, Malaysian media reported50 that the Malaysian military had noted the aircraft flying toward51 the country’s west coast.  That is far from where controllers lost contact with the plane.            
The next day, China released52 satellite images showing three large objects floating53 in waters between Malaysia and Vietnam.  But China later said it could not confirm the objects belonged to54 the missing aircraft55.           
The Wall Street Journal reported that the plane could have stayed56 in the air for several hours57 past the time of its last confirmed location.  The newspaper said later that the plane continued to send information about its engines58 and performance to satellites for five more hours. 

That suggests Flight 370 could have remained59 in the air or was on the ground60 somewhere61.  Why the signals stopped is unclear62. This is a developing story63. For the latest news on the Malaysian airliner, go to VOANews.com.
