Starship SN8
Test Vehicle
Starship SN8 was a test vehicle designed to perform a 12.5 km test flight. It became the first Starship to be outfitted with three Raptors (SN30, SN32, and SN39). After the first static fire, SN39 was replaced by SN36. After the third static fire, Raptor SN32 was removed due to an anomaly and replaced by Raptor SN42. Thus, SN30, SN36, and SN42 are the Raptors that performed the eventual test flight. During the flight, Starship SN8 was lost due to an anomaly with header tank pressure but completed many test objectives.

History
12.5km Test Flight
Starship SN8 successfully flew to around 12.5 kilometers in altitude, demonstrated a controlled descent, successful flip maneuver with Raptor engine relight, but had a hard landing due to lack of pressure in the header tank. The anomaly resulted in the loss of the vehicle.

Static Fire #4
Static Fire #3
Starship SN8 performed a static fire using the LOX header tank in the nosecone. An anomaly with a Raptor engine (caused by flying debris from the pad) during the test resulted in a loss of vehicle pneumatics. The LOX header tank was thus unable to properly vent until it blew its burst disk.

Static Fire #2
Starship SN8 performed a static fire using liquid oxygen (LOX) fed from the nosecone header tank. This was the first-ever use of a LOX header tank on a Starship vehicle. As such, this static fire only featured one of the three engines installed on SN8.

Cryogenic Proof Test #3
Starship SN8 successfully passed the cryogenic proof test, according to SpaceX CEO Elon Musk. The pass came after two previous attempts necessitated a redo. The cryogenic proof test ensured that the vehicle was ready for the upcoming static fire test campaign.
