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. Ya scallywag! T' aluminum engine is incredibly light compared t' more common copper-chambered engines. Begad! Night firings are so nice, they really show off t' mach diamonds. Avast, me proud beauty! This is near full throttle. Ya scallywag! It be a three second firing, ya bilge rat, and this is video at 300 frames per second, ya bilge rat, or 1/10th speed. Aye aye! That's also why thar's no sound, as it doesn't record t' audio at high speed.
