Video highlights an alleged X-classified detour by flight DP407 en route between Moscow and Yekaterinburg on November 11.
Kremlin-owned RT called it a “balloon flight path” but questioned whether the alleged stunt was “a little too arrogant”.
“This is probably how the Pobeda captains have expressed their support for Russian team captain Artem Dzyuba and shown their attitude in the face of intimidation,” an airline spokesperson said.
It was later confirmed that the Federal Air Transport Agency was investigating the “phallic demonstration” against the city of Neftekamsk.
Reports suggest that the crew requested clearance for the aerial maneuvers “due to the need to check the radio navigation equipment”.
It is known that the regular flight with the low cost airline Pobeda – which is part of the national airline Aeroflot – landed 20 minutes late in Yekaterinburg.
Oleg Panteleev, executive director of the Aviaport agency, told RBC media that a check was underway to see if the crew had been cleared for unusual maneuvers around Neftekamsk and, if so, whether the turns in the sky threatened security.
The investigation will also verify if the crew crossed the limits of ethical behavior.
Roman Gusarov, editor-in-chief of avid.ru, said: “You have to be crazy to perform such maneuvers.
“This kind of thing is severely punished.”
He added that if this was true, the waterfall seemed “extremely dangerous because the traffic density is high and the air corridors are narrow.
Mr Gusarov said: “Besides, to draw something like that and then admit it is to confess your hooliganism.”
Meanwhile, the FSB’s security service is investigating whether the 32-year-old Zenit St Petersburg player was blackmailed by $ 5 million because of the compromising video that was allegedly hacked from his cell phone. .
The married player is said to have met a hacker responsible for the theft of the intimate images, but refused to pay the ransom.
