Malaysia on Thursday released its most comprehensive account yet of what happened to missing Flight MH370, in a preliminary report that detailed the route the plane probably took as it veered off course and revealed the confusion that followed.
It showed four hours elapsed between the first sign that the Malaysia Airlines jet had failed to report in as expected and the decision to mount a search operation — and that time included lapses of communication and a false lead from the airline itself.
The document, dated April 9, also contributed to a growing safety debate by urging the International Civil Aviation Organization (ICAO), the U.N. body that oversees aviation, to consider introducing a system for tracking commercial jets.
