An analysis of the plane’s flight-data and cockpit-voice recorders was needed for investigators to determine why the engines appeared to lose thrust quickly after takeoff.

"This research would also not have been possible without the support of the Hawaiian Monk Seal Research Program, who deployed and retrieved the acoustic recorders in the Papahānaumokuākea National Marine Sanctuary."

Investigators have recovered the flight data and cockpit voice recorders -- the plane's black boxes -- which have been brought to Ankara for examination, the ministry said.

Now it is impossible not to notice them - mic-ed up, with video recorders on their chest, and even making announcements to the crowd.

The report will typically draw on information gleaned from examination of the crash site, for example, as well as basic material downloaded from the flight data recorder.
