The emergency Russian plane, the first to bring back the bodies of those who died when the A-321 plummeted from the sky above the restive Sinai Peninsula, arrived in the Pulkovo airport of Russia's second-largest city.
Investigators from several countries have joined an Egypt-led probe to determine what brought down Russian airline Kogalymavia's flight 9268 on Saturday, killing all 224 people
on board, en route from Sharm el-Sheikh to Saint Petersburg.
They have recovered the 'black box' flight recorders of the Airbus, and the head of an Irish mission that will join the Egypt-led probe into the disaster said the results from the recorders should be ready in a few days.
The head of the Russian air transport agency Alexander Neradko on Sunday said it appeared the aircraft disintegrated while flying at high altitude, echoing similar comments from other top aviation officials.
"All signs prove that the structure of the plane disintegrated in the air at a high altitude," he told Russian state television.

The bodies of those sent back to Saint Petersburg were due to be taken in a motorcade to a crematorium for identification, which will begin later today, according to Russia's emergency ministry.
Russian officials confirmed that 144 bodies were on board the plane that landed at Saint Petersburg, after the worst aviation disaster in the country's history.
Egypt had earlier said the remains of 162 people would be flown back, out of 214 Russian passengers said to have been on the flight, along with three Ukrainians and seven crew.
