KUALA LUMPUR - Malaysia on Thursday made public a report on Flight MH370 and other data in its most extensive release of information on the airliner yet, but which contained no new clues on what happened to the missing plane.
The brief five-page report dated April 9, and which was submitted earlier to the International Civil Aviation Organisation (ICAO), was mostly a recap of information that had already been released over time.
It contained no major revelations in what remains one of the greatest mysteries in aviation history.
"Over a month after the aircraft departed Kuala Lumpur International Airport, its location is still unknown," the report said.
The Malaysia Airlines flight vanished March 8 en route from Kuala Lumpur to Beijing with 239 people aboard.
It is believed to have crashed in the Indian Ocean, but a massive search for wreckage has been fruitless.
The information release was accompanied by audio recordings of verbal exchanges between the cockpit of the jet and air traffic controllers, and documents pertaining to the cargo manifest.
The collected information also recapped exchanges between the flag carrier and confused Malaysian, Vietnamese and Cambodian air-traffic controllers as they sought to determine what happened to the plane after it disappeared from primary radar over the South China Sea at 1:21 am on March 8.
The main report is required by the ICAO within 30 days of a crash, and Malaysian authorities have confirmed it was submitted on time.
However, they waited another three weeks before releasing the brief document, with Prime Minister Najib Razak saying last week he wanted it to be reviewed first by an "internal" team of experts.
Recommendation on real-time tracking
Malaysia's long-ruling government, which has a poor record on transparency, was heavily criticised for a seemingly chaotic response and contradictory statements on MH370 in the early days of the crisis.
It has been tight-lipped about the progress of its ongoing investigations.
