What happens when cryogenic propellants rupture upon impact due to rapid depressurization?

Answer

They flash into gas extremely quickly, creating an energetic mixture.

Rapid depressurization and warming cause the cryogenics to flash into gas extremely quickly; gaseous methane then mixes with ambient air and available liquid oxygen, creating a massive, highly energetic fuel-air mixture.
