Carbon Freezing

Directory Facilities for carrying passengers in cold sleep may be installed in a traveller class starship. One low passage berth carries one passenger, and is usually more cost effective than staying in a stateroom.

Low berths also serve well in emergencies in that they can provide suspended animation facilities for people when medical care, rescue, or assistance is not immediately available.

Carbon freezing is being cryogenically frozen and stuffed into a tube to be unfrozen at your destination.

It is not unknown for low passengers to die in transit, whether from the system shock of being frozen, being improperly revived, or from malfunctions in the low berth.
