Interesting thread: https://twitter.com/KarenSBernstein/status/1512454357865963528QuoteSpaceX benefited tremendously from our NASA collaboration as part of @Commercial_Crew. Their spacecraft design succeeded because of their smart and hard work, but also because top JSC engineers partnered with them all the way.Boeing did not allow collaboration in the same way. I was the spacecraft struc mech system manager on the nasa side. These 2 companies had very different relationships with my team.Boeing believed it had all the answers, did not appear to understand the nature of a fixed price contract, and treated my team like people they hardly needed. SpaceX welcomed wisdom and guidance and fully partnered with our engineers.To be clear, by “Boeing” I mean mgmt. the engineers we worked with were just as frustrated as we were.

There was a discussion early on that Boeing was going to be excused from strict NASA oversight (good), while SpaceX was stuck with it (bad). I could see how they could end up in this situation.John

On July 7th 2020, the outcome of the Starliner investigation was discussed during a teleconference. During that teleconference Steve Stich (then Commercial Crew Program Manager) admitted "that NASA felt more comfortable with Boeing's traditional approach, so SpaceX may have had more oversight since they had a newer approach."https://twitter.com/nextspaceflight/status/1280580214729261058
Is there a published source anywhere that compares the turnaround costs other than LVs of Crew Dragon versus Starliner? Not launch costs (F9 versus Atlas V or Vulcan), but cost of recovery (water versus land), capsule refurbishment, and replacing expendable units (trunk versus service module). We can guess that water recovery is more expensive, that a Starliner capsule might be cheaper to refurbish, and the trunk is cheaper than the service module, but guesses are not substitutes for good sources.
Bottom line is that I don't think we'll ever know.

NASA will probably need reminders to stay honest.
[...]And yes, it is absolutely right to periodically remember people of this. Because this preferential treatment of one's system, over that of others, is being repeated by NASA as we speak. Just look at how NASA is proceeding with the SLS WDR. They now plan to complete the WDR as a "partially dry WET Dress Rehearsal". The rationale behind this decision supposedly being that the ICPS stage is known inside-and-out (given it being a converted DCSS). I wonder what ASAP thinks of that decision and the supporting rationale.
The argument at the time was that NASA oversight was onerous and expensive. Private companies did not need it. Few would believe that close NASA involvement would end up saving time and money.John
I wonder what ASAP thinks of that decision and the supporting rationale.

NASA will probably need reminders to stay honest.Emphasis mine. Yes, it is general knowledge NOW, exactly because of the teleconference I mentioned. But PRIOR to the comedy-of-errors that was OFT-1, it had long been suspected that NASA was giving Boeing the preferential treatment.Not until Steve Stich pubically acknowledged that this was in fact exactly what had happened, has it become a public fact. And yes, it is absolutely right to periodically remember people of this. Because this preferential treatment of one's system, over that of others, is being repeated by NASA as we speak.

Many of the negative habits people associate with "government organizations" are equally present at very large corporations - I've seen it often enough.
Quote from: woods170 on 04/11/2022 09:48 am I wonder what ASAP thinks of that decision and the supporting rationale.It is an uncrewed flight. So the ASAP has no real play in it. Much like not doing a WDR for other rockets, it is only a schedule risk. If a problem crops up during the countdown, the necessary actions will be taken such as delay, scrub or even rollback. If this mission were to be crewed, then a different posture would be taken such as a completely successful WDR before entering actual launch ops.
