The sound of a jet engine building towards take off underscores moments where there is no turning back. A skier leaning over the edge of a cliff. A presenter about to walk on stage before a large audience. A rocket scientist with his finger on the launch button. Time slows down, heightening the anticipation of these moments. The sound of the engines builds. Louder and louder to a mighty roar. There’s only one direction now. Forward. The skier tips over the edge. The presenter walks on stage. The rocket launches into the sky. And the engine roar suddenly goes quiet, like a scream becoming an exhale. We see the plane rise out of frame as it goes off into the world.
