A search for missing Malaysian Airlines flight MH370 is being called off next week. Two former airline executives say it's possible the plane will never be found.,

The conclusion raises the prospect that the search for the Boeing 777 could continue well beyond next month, when crews are expected to finish their deep sea sonar hunt of the current search zone west of Australia.

A Canadian aviation expert says the disappearance of Flight MH370 over two years ago was no accident.
