A top official at Metrojet, the Russian airline company whose flight crashed Saturday in Egypt, is insisting that a technical fault could not have caused the crash.
Alexander Smirnov, the deputy general director of Metrojet, told reporters Monday in Moscow that no technical fault could have caused the Airbus A320-200 to break up in the air.
He says the cause of the crash "could only have been a mechanical impact on the plane" in the air.
Russian investigators say the plane broke up at high altitude but have so far refrained from naming possible causes.
The Metrojet crashed Saturday morning 23 minutes after taking off from Sharm el-Sheikh, killing all 224 on board, the vast majority of them Russians.
