From what I read, they said the first stage was very smooth. They only said the second stage was rough compared to the shuttle after SRB separation. That makes sense considering the dampening effect of the orbiter and ET's mass compared to the Dragon and 2nd stage.

Wow, yeah, the mass to orbit (or near orbit) with the shuttle was pretty huge. What, about 99 tons for the orbiter and I really don't know the dry (or near dry) weight of the ET. Of course, the ET was dumped as they reached orbit, but still, it was 'along for the ride' into orbit, so yes, as you say, that combined mass would have done an awful lot of dampening. Still, from the shuttle in-cabin cameras during some of the latter years of the program, we all know that even THAT vehicle could bounce around some at liftoff! For all the shuttle *didn't* do, it still represented an amazing set of technology. It's still hard to believe that 4.5 million pound stack doing 90mph as it cleared the tower. And then Mach 1 in about 45 seconds or so. Amazing. Earl

I was not a fan of the shuttle program because it shoveled dirt on manned missions beyond LEO with the Saturn V. As the program ended, I did become a fan of its capability to haul huge items to LEO and back home again, not to mention save NASA's bacon with on orbit repair of Hubble. I hated that it ended without a replacement even on the horizon. It was expensive, but it was a beast. Not a Saturn V beast, but nothing ever will be. 6.2 million pounds at liftoff on 7.6 million lbs of thrust and to the moon in the slide rule era of late 1968, only 6 years and 3 months after Kennedy threw down the gauntlet. Now that's a beast! I'm ready for Dragon's next manned flight and I hope Space-X progresses from this flight with the Falcon 9 to the moon with Starship as fast as NASA did from Mercury Redstone to Apollo 8. Elon is shooting for four years!

Absolutely! Nothing beats a Saturn V. Back in the 60's when my father worked for the Boeing Company on the S-IC boosters at the Michoud Assembly Facility in New Orleans we watched ALL the launches. The achievement of creating such a "beast" still amazes me to this day and it will for the rest of my life.

Yeah, as of last night they were still targeting the Atlantic, off the coast of FL. That really did not seem like any kind of plausible area to shoot for, what with the hurricane. But, I guess they were fully sizing up alternatives before officially announcing that yes, we will NOT be aiming for any location on the eastern size of FL with a hurricane blowing around.

Deorbit burn started. Splash down in about 45 minutes. Good luck guys!
Forty-five years and essentially a week since the last American manned splash down, Apollo-Soyuz in late July, 1975. Earl
