As the rocket attempts a landing, one of the engines fails to light and the thrust turns green, apparently meaning the engine is eating itself. "Engine Rich Exhaust" as the copper in the engine starts to burn away. It is theorized the engine failures resulted in a overly rich oxygen mixture that just corroded the metal in the engines toward the end. 2 Share this post Link to post Share on other sites

(I keep thinking of the cost of having to build three new Raptors, though.) At this rate, I may yet get my flying car. Share this post Link to post Share on other sites

Manley qualifies this in the vid. Not so in this particular case, allegedly. Share this post Link to post Share on other sites
