Hyderabad, Mar 13 (ANI): A Senior Boeing official allayed concerns over the safety of their planes amid the mystery surrounding the fate of the missing Malaysian jetliner, saying they had also joined the global search operation covering an area stretching from China to the Andaman Sea. Five days after Malaysia Airlines flight MH370 disappeared from civilian radar screens, a huge international search operation has failed to turn up a trace of the Boeing jetliner that was carrying 239 passengers and crew. Senior Vice President, Sales, for Asia Pacific at Boeing, Dinesh Keskar said he would not like to speculate on what could have possibly happened to the missing plane, saying that would be unfair to the families of the passengers on board the vanished aircraft.
