In Alien: Covenant an alien creature is trapped inside a crane during one of the final scenes where the ship tries to fly away from the planet.
At some point, something unclear happens (the camera shakes a lot during this scene) and the alien dies. I understand it has something to do with the crane, but I am not sure what. If it's simply crushed by the crane, why doesn't this happen sooner?
What exactly happens at this moment and how is this explained?
