Help with movie name

Hi Everyone, I'm new here and am a big fan of guns in movies.

Recently I've been stumped and can't figure out the name of this movie that has an awesome sniper/shooter setting. Thought I would give you what info I have to see if any experts here can figure it out.

Pretty much the movie takes place during the day and a sniper is aiming for a target (possibly a political official) exiting a plane at an airport that is a great distance away. He takes the shot right as the target is standing at the door opening of the plane. I want to say that some of the shots he makes even penetrate completely through the plane.

I might have two movies confused, but I think the sniper is using a gun that is mounted to a tripod.

Thanks!
