Kuppam

Kuppam was an artificial world built in Earth's orbit by the Yamoyata Company. It was a steel and glass spheroid with a stationary casing of lunar rock. The hollow interior was inhabited, and boasted woodlands, rivers, hills, bridges and towns. One of the light-alloy bearings used to support the junctions between the static outer shell and the rotating interior snapped, causing the shell to be breached and to collapse, 50595 people died as a result.
