  1. That’s not clear. Certain dynamic instabilities (such as pogo or resonant oscillations in fuel lines) did not show up in the static tests of previous rockets, such as the Saturn V, and were only seen in flight. This SpaceX announcement said they were *attempting* to induce the dynamic resonances in the fuel lines during this static test to see if they could duplicate what was seen in flight 7…it does not really say if they were successful in duplicating the effect. Flight 8 will tell.
  2. I remember when we were told definitively and repeatedly in this thread that it was IMPOSSIBLE for a cylindrically shaped vehicle to maintain stability during reentry. This turned out not to be the case. Now we hear definitively and repeatedly that every eruption of flame or propellant distribution problem is the result of some catastrophic Raptor failure. This, too, shall pass.
  3. It matches my memory of the liftoff speed of a Saturn V (the only video I can easily find of the Saturn V right now are slow motion movies). I presumed they were doing it to go easy on the engines, since they had almost no payload. Or maybe so that somebody here could rant about how they are lying about the actual thrust capacity and reliability (since they failed to relight for landing) of the BE-4 engines. But I don't see that rant. Odd.
  4. Top 10 tallest rockets is missing the Apollo Saturn IB.
  5. Loading propellants? Wow. Even if it’s just liquid nitrogen…I’m surprised the quick disconnect plumbing is still in working order, considering the way it was belching flame like crazy as the booster was landing (and for several minutes afterward). I guess maybe it’s supposed to flame like an angry dragon despite that looking like an undesirable anomaly.
  6. In replays I can see where the part of the chine is breaking apart during booster landing burn…so that damage wasn't from hitting the tower.
  7. How long are the Raptors supposed to keep smoking?
