SpaceX StarHopper engine test and unexpected fireball (4K Slow Mo)

SpaceX performed a test of their StarShip prototype vehicle known as StarHopper with a brand new serial number 6 Raptor Engine. The vehicle was tethered and held down (hence static fire). The engine test appeared to go well at approximately 10:24 P.M. local central time and seems to have gone for the full duration. For 4 minutes after the engine test, the vehicle remained on fire until suddenly a large fire ball appeared. Damage to StarHopper is unknown at this time. Feel free to use this footage for yo
