   Actually just the opposite, low fuel, oxidizer rich, or as some joked,   
   "engine-rich" which it basically was, the oxygen rich flow started to   
   consume the engine (probably the copper though apparently there's some   
   speculation it was another metal in the engine which I forget what it might   
   be.)
