PARIS, March 24-- The first black box of the crashed Germanwings flight, which has been found by gendarmes at the site of the disaster, is used for recording conversations in the cockpit, local media reported on Tuesday.

The other black box, which is used for storing flight data, has not yet been retrieved by the gendarmes, BFMTV reported Tuesday night.

Search and rescue operations have been currently suspended but will resume Wednesday morning.

An Airbus 320 plane of German budget airline Germanwings with 150 people on board crashed in southern France on Tuesday while en route from Barcelona to Duesseldorf. No survivors are expected.

The flight was scheduled to arrive in Dusseldorf at 11:35 a.m. local time (1035 GMT), but started to descend one minute after reaching its cruising altitude of 38,000 feet at 10:45 a.m.

The aircraft was delivered to Lufthansa from the Airbus production line in 1991 and transferred to Germanwings in 2014. According to media reports, it was one of the oldest planes in Germanwings' fleet.
