It is really tough to figure what is going internally at Boeing. I know my ex-BIL was ordered to move from Manhattan Beach(McDonald-Douglas) to Seattle, but he choose to take early retirement because his reasoning if he made the move, there is no guarantee how long they will keep him.
Also for many years here on ARFCOM, we have had ex-Boeing engineers claim he was laid-off and a DEI-replacement was hired in his place. Personally, the solution to Boeing's problem is to cut loose everyone from the CEO down to the janitor, and repopulate it with engineering people. |

I know it's been discussed but how difficult is it for SpaceX to throw 2 extra space suits into their capsule? They must have every measurement possible of the two guinea pigs in space in a fitting manual for the Boeing suits. Cheap? No. But it shouldn't be insurmountable.

Sure keep classified things classified, but all they've said about the thruster issue is: Ground testing conducted on thrusters that maneuver Boeing’s capsule in space found that Teflon used to control the flow of rocket propellant eroded under high heat conditions, while different seals that control helium gas showed bulging, they said. It's bullshit artificial opaqueness that does nothing other than erode the public's confidence in a once great institution.

Quoted: No it's not, management is doing what they think is best for Boeing. "best" may or may not involve building the best airplanes and spaceships ever. No they aren't. I'm a taxpayer and I want to know what they are doing with my money. Sure keep classified things classified, but all they've said about the thruster issue is: Why haven't other spacecraft had this same problem? Is the teflon in question thread sealant or is it seals inside valves or fittings? If it erodes under heat more than they anticipated how do they know it won't erode enough to cause a problem during the return trip? Is the teflon erosion the cause of the inoperative thruster? Where are these teflon parts located? How do you know the helium seals won't degrade further during the return trip? How much helium is currently on the starliner and how much is needed for the return trip? Where are the leaks and what are the actual leak rates(in mass per unit time)?

Historical context. https://www.cbc.ca/news/science/nasa-discussed-not-telling-astronauts-about-columbia-s-doom-1.1390174 "You know there is nothing we can do about damage to the (thermal protection system)," Hale quotes Harpold a decade later. "If it has been damaged, it's probably better not to know. I think the crew would rather not know. Don't you think it would be better for them to have a happy successful flight and die unexpectedly during entry than to stay on orbit, knowing that there was nothing to be done until the air ran out." They told astronauts they weren't worried about damage from foam insulation coming off the massive shuttle fuel tank during launch, hitting a wing that allowed superheated gases in when the shuttle re-entered the atmosphere. No one was aware of the seriousness of the damage at the time. This was a what-if type question that conveyed a fatalistic attitude about the heat shield system being unfixable, which was "a wrong-headed cultural norm that we had all bought into," Hale said in a Thursday telephone interview. |

Reentry isn't the concern. It's a timely reentry that's the question. Or banging into the ISS as you pull away, which has heretofore been purely a Russian concern for Progress. |

The rub here is that if they get off the ISS OK and their thrusters cant complete the de-orbit burn correctly you got two outcomes. It comes down somewhere its not meant to do and you hope you come down on land or you are stuck in space. The first is a problem cause that thing ain't meant for a water landing. The second is there is nothing you can do about it. You cant just send up dragon, rendezvous and then just change capsules. There are no suits in that thing rated for space and neither capsule is built to depressurize and represurize it self. So even if you could get close, life support is still an issue.

So without the needed cooling and support structures of the suit, how do they deal with the temps and vacuum of space without turning into that kid from a christmas story.
