Not like most of other think, there was no CGI in the airplane stunt in the movie: Mission: Impossible – Rogue Nation. Everything was real! In fact, this stunt was extremely dangerous, as Tom Cruise was strapped outside a plane took off at 300km/h!

The crew made a special camera rig and mounted it to the Airbus A400. It was mounted strongly to ensure that no danger would happen to the actor. 

In the interview with yahoo Movie UK, Tom Cruise said that the main concern was about the flying objects and birds, as they could injure or even kill him. It was on the second take that "I got hit by just a little particle". "I literally thought it broke my ribs" he said. The actor also wore special contact lenses that protected his eyes from tiny particles.

Initially, Airbus was reluctant to loan the A400 to the production; it would hardly be good publicity for its sleek new aircraft if one of the world's biggest movie stars tumbled off it at thousands of feet. But then, the film crew managed to limit risk, and persuade Airbus everything would be alright.

The scene actually took eight takes/takeoffs to complete. "I was actually scared shitless," Cruise told a crowd at CinemaCon at Caesar's Palace in Las Vegas "I was in a harness, on my side, that was kind of loose so you can see the vibration of my body against the plane."
