A recent observation of a jet seemingly disappearing into a "wormhole" is explained as a visual effect caused by the plane breaking the sound barrier. This phenomenon occurs when a conical vapor of water and atmospheric gas is emitted from the jet's nose, creating a symmetrical cone shape that gives the illusion of the plane vanishing. The vapor trail's visibility can vary based on the aircraft's design, particularly how it manages airflow around the wings and nose. This effect is linked to sonic booms and the interaction of sound waves with the surrounding air. Understanding these dynamics clarifies the misconception about jets disappearing into wormholes.
