Iran has asked the US and French authorities for equipment to download information from black boxes on a downed Ukrainian airliner, a request that will add to international frustration at Tehran's failure to send the recorders abroad for analysis.

Iran said on Sunday it was trying to analyse the black boxes of a Ukrainian airliner that its military shot down this month, denying a report that a decision had been taken to send the voice ...

The black boxes for the tanker Sanchi and the freighter CF Crystal, the two vessels that collided in the worst oil ship disaster in decades, have been opened, the Iranian Students’ News Agency reported.

The black boxes from an EgyptAir jet that crashed in the Mediterranean last month will continue emitting a signal from beneath the sea until June 24, a statement from the Egyptian investigation committee said.

The search zone for the crashed EgyptAir jet has been narrowed to 2 km from 5 km after a vessel picked up a signal from one of the black boxes, an Egyptian source on the investigation committee said on Thursday.

Egypt has hired a private firm to help find EgyptAir MS804's black boxes in an area narrowed down by an emergency signal sent when it hit the Mediterranean last week.
