Moscow, December 18

In the presence of foreign experts, Russian officials today opened the damaged black box of a warplane shot down by Turkey, promising a transparent probe into the incident.

Russian officials opened the orange-painted flight recorder as experts from China and Britain watched the procedure, an AFP correspondent saw.

Wearing lab coats, technicians used screwdrivers, drills, and even a vacuum cleaner as they opened the device under the watchful eyes of military personnel and dozens of journalists in a live national television broadcast.

The findings will be revealed on Monday, the air force said.

Sergei Dronov, the deputy head commander of the Russian air force, said the device was being analysed “openly for the Russian and international public” after President Vladimir Putin had ordered that it be opened only in the presence of foreign specialists.

Moscow and Ankara have been locked in a bitter spat over Turkey’s downing of the Su-24 jet on November 24, which led to the deaths of a pilot and another serviceman who attempted to rescue him.

They were Russia’s first combat casualties of the Syrian campaign.

Turkey says the Russian jet strayed into its airspace and ignored repeated warnings, while Moscow insisted it did not cross over from Syria and accused Ankara of a planned provocation.

“We have sufficient evidence that proves that the Russian aircraft did not violate Turkish airspace,” said Dronov, adding that the downed plane had been flying in Syrian airspace 5.5 kilometres from the border with Turkey. Dronov said the black box presented to the public today had not been touched since it was recovered from the crash site.

The air force commander said 14 countries had been invited to monitor the investigation but only China and Britain had accepted the offer.

US experts were also present when the black box was opened.

The military said the black box had sustained damage, including multiple scratches and dents, but had not been exposed to the fire at the crash site. Putin has said an analysis of the black box would help determine the downed jet’s flight path and position, which Ankara and Moscow have furiously disagreed upon.
