Flight MH370: No explosion or crash detected, UN N-watchdog says - The Times of India
A UN-backed nuclear watchdog has said that it did not detect either any explosion or crash that could be linked to the missing Malaysia Airlines plane, amid continued speculation over fate of the aircraft.
"Regarding the missing Malaysian Airlines flight... the Vienna-based Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) confirmed that neither an explosion nor a plane crash on land or on water had been detected so far," Spokesman for UN secretary general Ban Ki-moon Stephane Dujarric told reporters here on Monday.
Dujarric said plane accidents may be detected, depending on individual circumstances, by three of the four technologies used by the CTBTO's International Monitoring System (IMS).
While the verification system has been put in place to detect nuclear explosions, it is also able to detect the explosion of a larger aircraft, as well as its impact on the ground or on water.
CTBTO executive secretary Lassina Zerbo had last week said that he would put the sensors of the organization at work to see if a possible explosion at high altitude of the missing Malaysian Airlines plane could be detected.
