Anger as probe report offers no new clues

Investigators said yesterday they still do not know why Malaysia's Flight MH370 vanished four years ago in aviation's greatest mystery, sparking anger and disappointment among relatives of those on board.

In a long-awaited report the official investigation team pointed to failings by air traffic controllers, said the course of the Malaysia Airlines plane was changed manually, and refused to rule out that someone other than the pilots had diverted the jet.

But after years of fruitless searching for the Boeing 777 that disappeared in March 2014 with 239 people aboard, the report offered nothing concrete to grieving relatives of passengers and crew hoping for some sort of closure.
