Turbulence

Turbulence is the fourth level in Call of Duty: Modern Warfare 3. The player starts off as Andrei Harkov, an FSO agent, on a plane with the Russian President, Boris Vorshevsky, speaking to his daughter about the peace conference in Hamburg.

Walkthrough
Harkov is one of the President's bodyguards, similar to a Secret Service detail. In the next room the player enters, President Vorshevsky sits down with a group of men discussing the planned peace with the west. His sentence is suddenly interrupted by gunfire as the plane is attacked by hijackers in an attempt to kidnap the President. The President is pushed to the floor, and the agents attempt to safely evacuate him, but the plane loses control, and is forced to make an emergency landing. The plane then crashes into a open field, and many of the F.S.O agents are dead or injured. After exiting the remains of the plane, the player must search for the President. Once the player secures the President, a helicopter lands to evacuate the President and the player. After opening the door to the helicopter, the player discovers that it belongs to Makarov, who then proceeds to shoot the player and capture the president. While the player is lying on the ground, wounded, you can overhear conversation between Makarov and President Vorshevsky. Makarov demanded the launch codes to secure his dominion over Russia and turning the tide against the West. However, the President refused to give up the launch codes, instead calling Makarov a madman. Furious with his stance, Makarov ordered his men to find Alena Vorshevsky. As Harkov tried to reach his gun, noticing his movement, Makarov shot him for a second time, killing him.

Trivia

 * This is the first appearance of President Boris Vorshevsky, who had only been referred to in the previous game.
 * This is the first time in the entire COD series that the player receives an "Objective Failed" text without death or penalty during gameplay; not just once, before the plane crash lands, but TWICE when Makarov comes out of the helicopter. The player can also get this the third time in Stronghold if he fails to time the explosion with the thunder.
 * If the player looks out of the windows before entering the briefing room, one can see four MiG-29s escorting the plane. When entering the room right after the briefing room, one can still see the MiG-29s, but they pull up and climb away, and they are never seen or heard from for the remainder of the level.
 * When the player opens the helicopter's doors at the end of the mission, the player will notice that when looking at Makarov, his name is shown as if he was a friendly.
 * At the beginning of the level, just when the player enters the conference room, there may be a guard named Dimitri Petrenko.
 * This is the second time you can physically see a president during a mission, the first being in U.S.D.D. in Call of Duty: Black Ops.
 * This level bears many similarities to Air Force One.
