Shipyard worker trapped in hull
One of the many myths surrounding Titanic is that a shipyard worker was accidentally trapped in the hull of the ship during construction.
The story is false, but may have originated in the routine tapping of rivets at the end of each day to check that they were correctly fitted.
The sound of this tapping may have encouraged older shipyard workers to tease the younger employees with stories of trapped workers tapping in hope of rescue.
