Heh, thanks! I’d not looked yet, so, quite a time saver.

There is always.going to be flames after landing. Rocket turbo pumps spin at 100,000+ rpm you cannot just turn one off. The spinning mass needs coolant and lubricant both of this functions are provided by the fluid being pumped through it. When you shut down a rocket you flow fuel or lox until the pumps spin down. You vent those over the side while that happens. You see that on every falcon 9 landing as the yellow flames flickering under it. You just saw it on a grand scale when ten raptors of three times the thrust spun down and then three more after the catch. Look up at the vents you can see the vapor coming out before it gets lit up by the running engines or the fact that it just went through a turbine at hundreds if degrees F too. Rewind the video look at the booster right after it stages and all the engines cut off. You see a huge white plumes being vented out the sides...That’s all the turbines spinning down and venting gas to space.

Thank you...

That was my initial impression. Nobody on any broadcast was talking about it, so I assumed it was nothing to worry about.

But I always see those flames, so I figured that was par for the course.

I STILL cannot get over the grand scale of what we saw yesterday morning. Just amazing.
