   Still, while it unequivocally proved that SpaceX is on the right track,   
   both the lead-up to Starship SN5’s hop and the hop itself hint that a   
   few kinks will still need to be worked out. Notably, during SN5’s hop,   
   part of Raptor engine SN27 appeared to catch fire at some point after   
   ignition, producing substantial flames that lasted for at least 10   
   seconds. For any rocket engine, an onboard fire is always a   
   possibility, but most engines are either designed to tolerate the   
   inhospitable environment they create or heavily insulated from it.

   despite the progress SN8 is making.
