I would love to know how they prevented flow separation when they fired a vacuum optimized engine at sea level! Normally the pressure at the end of a vacuum nozzle is so low that the ambient air pressure will separate the flame from the nozzle and destroy the engine! @elonmusk

Raptor has a very high chamber pressure, which in turn allows for a large expansion ratio nozzle without flow separation at sea level
