> It is obvious in the video as the engine exhaust became bright green at the end, a sign that the engine was restarting by TEB. They wouldn't carry enough TEA/TEB to make that much flame - it's likely the engine itself burning. Also I don't think Raptor uses TEA/TEB as that would put a cap on the number of restarts - not something you want for an interplanetary mission!
