T' last firin' o' t' evenin' with t' new aluminum chambered engine on Masten Space Systems' XA-0.1B-750 single engine VTVL flight demonstrator. Avast! T' aluminum engine is incredibly light compared t' more common copper-chambered engines. Avast! Night firings are so nice, matey, they really show off t' mach diamonds. Avast, me proud beauty! This is near full throttle. Arrr! It was a three second firing, and this is video at 300 frames per second, or 1/10th speed. That's also why thar's no sound, matey, as it doesn't record t' audio at high speed.
