The Biliskner crashed into the Pacific Ocean about 400 miles off the coast of California.
When the Biliskner became infested by Replicators and sent on a course toward Earth, SG-1 assisted Thor by destroying the deceleration drive, deliberately causing the ship to accelerate out of control and burn up in Earth's atmosphere. The Biliskner was Thor's Asgard mothership which SG-1 first witnessed when it appeared above Cimmeria, an Asgard protected world.
Because the controls were so intuitive, it was possible to pilot a ship almost single-handedly, and often Asgard motherships did not require a large crew for operation. Most of the ship's systems were controlled by a series of small rounded stones which activated systems as they are moved into position on a control panel. They were powered by four neutrino ion generators and were equipped with powerful defensive shields, transport beam technology, sensors, communication systems which included holographic projection, medical systems including stasis pods, as well as a sophisticated cloaking device that enabled them to avoid detection from satellites and telescopes when in orbit around Earth. Enormous and powerful, Asgard motherships were more formidable than Goa'uld ha'tak vessels and were legendary among the Jaffa.
