It's almost as if a hardware-rich development program is a good thing. SpaceX had many Dragon flights before people were onboard, and they blew up a capsule before people were ever on board (unintentionally), and fixed those problems. The Space Shuttle flew first flight ever with humans on board. With relatively few contracted Starliner flights, they ought to be working most of the bugs out just as they get to their last flight. Assuming the get that far.
Edit: Grammar
Dragon 1 was a completely different spacecraft.

I think that is the point. It is much simpler to build Dragon I first. Walk before you run.

I consider Dragon 1 and Dragon 2 to be more similar than the Apollo command module blocks 1 and 2. In some ways the Dragon 1 capsules could be considered a prototype for Dragon 2 - especially in the case of the two or three last Dragon 1 capsules to be made.

* 04 Apr 2019 The Government of Ethiopia announces that pilots followed all Boeings procedures while trying to right the plane.
#1. NEVER give credibility to a 3rd world government's statements about how "their employees did everything right." They didn't. NTSB had a tough time getting to the data from the Ethiopian government, and when they did they found out that did do the correct procedure (amongst other things powering down the runaway trim system and trimming manually), THEN TURNED THE SYSTEM BACK ON when the manual trim system was hard to turn.
2. There's no need to bring it up. Starliner's problems are evidence enough that Boeing's still got problems to sort out.

Not that different. Key thing to me (as relates to this topic) that was similar were integrated propulsion systems. It gave SpaceX not only experience with thrusters, but also the ability to inspect them post-flight.

Just a reminder.
Again.
This is for mission updates and discussion.
There are separate threads for big picture stuff.

And to triple-lock this point, anyone who brings up the 737Max as an attempt to back up their dislike of Boeing or Starliner is not going to be posting on here much longer. Fair warning.

Recap on 5 RCS aft thrusters failed in final phase of docking.
D1A3(?) 11% on first firing and 0% on second. Deactivated for remainder of flight.
A lot more on other thrusters, how they were tested, etc. One interesting note is that telemetry is at 10hz so there is an absence of peak thrust data due to the low resolution.

Taking time to do hot fire testing and gather as much data as possible due to loss of thrusters on SM. Docking day looked more stressful on the thrusters in comparison with OFT-2. Running a lot of simulations.

On helium leaks, one more leak, smallest of the leaks, very small. Isolated helium manifolds, looked at leak rate, leak rates have gone down on all of them during the nine days docked. Appear to be related to thruster usage.

Have run dress rehearsals of landing and post-landing ops. Really comfortable with that part of the process.
