Plot
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. As President Vorshevsky is arguing with Vasili Zhukov he is 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 are tasked with defending him. After defending the room from attack after hijackers breach it, the President follows the agents to reach a safe room. The agents move through the plane's interior and they near the cockpit. But before they can reach it, the plane stalls, sending it plummeting down. This puts the inside of the plane in a temporary state of zero gravity.

After clearing the room of all the hijackers, the agents move downstairs, and fight their way through the kitchen and the cargo bay to rescue Alena Vorshevsky. The agents then start to engage more hostiles in the passenger areas 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 agents search for the President. Once the security team secures the President, a helicopter lands to evacuate the President. After opening the door to the helicopter, Harkov discovers that it belongs to Makarov, who then proceeds to shoot him and capture the president. While Harkhov is lying on the ground, wounded, he 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 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 Modern Warfare series where the player is affiliated with the Russian government.
 * This is the second time in the entire Call of Duty series that the player receives an "Objective Failed" text without death or penalty during gameplay, but the first time in the Modern Warfare series; not just once, before the plane crash lands, but twice when Makarov comes out of the helicopter. The first was in the Call of Duty mission "Brecourt Manor", where it was possible for Moody to be killed, failing an objective to cover him, but not causing you to fail the mission.The second was in the Call of Duty: World at War mission "Blood & Iron", if the player didn't destroy all the 88s and continue toward the road till train station.
 * If the player looks out of the windows before entering the briefing room, one can see four MiG-29s escorting MiGs_Turbulence_MW3.png 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.
 * This is the second time one 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 the movie.
 * This is the second level out of three in the series to be featured in a passenger plane, the others being Mile High Club in Call of Duty 4: Modern Warfare and Milehigh Jack, a Special Ops mission in Modern Warfare 3.
 * If the player stands too close to the edge of the airplane as it breaks into two, there will be an animation of the player tumbling out of the plane, and they will also receive a death text saying "Stay away from the edge to prevent falling out."
 * In the starting area, there is a glass display mounted on a wall. Inside the display are small models of a MiG-29 and a T-90 tank.
 * After the plane crashed and as you emerge from the wreckage with Commander Leonid Pudovkin, the player can hear radio transmissions from FSO agents talking about how the hijackers have breached the plane.
 * While onboard the plane, one of the enemies has a PP90M1 with every attachment on it. It cannot be obtained.
 * If the player looks at their minimap's compass, they will see that the plane is apparently flying north. However, if the plane was going from Moscow to Hamburg, it would be going west, not north.
 * The AK-74u has a unique reloading animation during the Zero-G sequence of Turbulence. The reloading animation shows the player throwing the magazine away and it spinning in mid air, as opposed to it simply falling off screen.
