Investigators still do not know why an Air France flight from Rio de Janeiro to Paris crashed into the ocean in June, according to an update released today.
The report is the second on the Airbus crash and families of some of the 228 victims say the probe is taking too long and want to know what happened.
The report says the circumstances of the crash and its causes “are still not determined. Investigative work is continuing to that effect”.
The report provides some clues. It says oxygen masks did not drop, and the plane did not depressurise.
All of the life vests found were still in their wrappers, suggesting perhaps that passengers had little or no warning.
It also says the aircraft was probably in one piece upon impact.
