   Yes it appears to have been running fuel rich. There's a bit of dark   
   smoke involved as well which can be seen in some of the ascent videos.   
      
   Also seems to have been a methane leak after bouncedown that eventually   
   ignited. Also there were seen to be excessive methane leakage even as   
   SN10 was conducting its single engine power down descent. It   
   occasionally flared up in flame at least twice and there was a fire   
   on-going after it came to 'rest' before the rapid unscheduled relaunch   
   and disassembly.   
      
   See Scott Manley video mentioned elsewhere in this thread for details.   
   As he points out (and I have to agree) the RUD appears to be due to an   
   oxygen tank pressure failure which ruptured both tanks, largely   
   propelled the SN10 re-aloft and trigger the subsequent explosion.   
      
   The landing 'legs' or pogos as I prefer to call them seem to be the next   
   issue now. Manley shows video that clearly shows several that failed to   
   lock into position and three that do.
