Omnistate impact chamber
From Tardis Wiki, the free Doctor Who reference
An omnistate impact chamber was a container that the Tenth Doctor called "indestructible", capable of enduring a supernova or the detonation of a nuclear storm drive.
Max Capricorn planned to use an omnistate impact chamber to live through the space cruiser liner Titanic crashing to Earth, as part of his "retirement plan". (TV: Voyage of the Damned)
