Hulk-proof Cell
The room contained a central reinforced chamber which could be released into empty air, intended as a last resort measure to kill the Hulk.
During the Attack on the Helicarrier, Loki trapped Thor in the central chamber and released it, sending him plummeting to Earth. However, due to his Asgardians physionimy, he survived the drop, suggesting it would never have worked to kill the Hulk.
