With Sasha still piloting the plane, the survivors drove out. Sasha managed to land the Antonov 500 right on the edge of a mountaintop. The top then crumbled, sending the plane to fall down, crash and explode.
While Antonov is a real aircraft manufacturing company, the "Antonov 500" is not a real model produced by the company. The plane shown in the film is a Antonov An-225 Mriya.
Although Yuri states that the plane is Russian, Antonov is actually Ukranian.
