KUALA LUMPUR: Malaysian Airlines flight MH370 dropped to an altitude of 5,000 feet, or possibly lower, to defeat commercial radar coverage after it turned back from its Kuala Lumpur-Beijing route on March 8, according to New Straits Times.
Investigators are poring over the flight profile to determine if it had flown low and used “terrain masking” during most of the eight hours it was missing from the radar coverage of possibly at least three countries.
Top officials are looking at the possibility that the jetliner had taken advantage of the busy airways over the Bay of Bengal. By sticking to commercial routes, the flight may not have raised the suspicion of those manning military radars of the nations it overflew. To them, MH370 would appear to be just another commercial aircraft on its way to its destination.
The person who had control over the aircraft has a solid knowledge of avionics and navigation, and left a clean track. It passed low over Kelantan, that was true, said officials.
