Let me ask a question that I cannot find an answer to. Is the Drago Crew able to perform a manual descent in the event of a loss of communication with the MCC or other emergency?Yes. See the buttons circled in Yellow. Image attached is a recreation of the control panel. Here's a link to an actual photo: https://forum.nasaspaceflight.com/index.php?action=dlattach;topic=46136.0;attach=1537705;imageyou want to say that it is enough to push one button and the Dragon will return home?Probably not while docked to ISS but if free flying I've no doubt it's default landing location is programmed in so that pushing the button executes the appropriate phasing and deorbits.If the computer system fails, then this scenario will be impossible.Yes. Obviously there are some (extremely unlikely) scenarios where the crew won’t survive. What are you angling for exactly here? You got an answer to your first Q, and now you are moving the goalposts?

can i see this "preflight mission sim for the inspiration 4 crew" somewhere?
... They all seem self-explanatory except for "Breakout." Can anyone enlighten me as to what that one is does and when it would be used?
Gerstenmaier said there was still one “action” to emerge from the review, regarding the performance of the flight software on the spacecraft as it approaches the ISS. He said one of the station’s international partners, later revealed to be Russia, had a dissenting opinion on the issue.He said the concern was about what would happened if there was a failure of the main computers of the spacecraft on approach, and how it would perform a “breakout” maneuver to avoid the station. He said the computers on Crew Dragon are fault tolerant, but that the mission team will “look a little more rigorously” at fault detection procedures. “I don’t think it will be a problem once we go through the details of why it’s safe,” he said.

Nice fly around graph after undocking
How long will the fly around take with the four burns?It could be done with a single burn, but that would take a full orbit, ~90 minutes.Now, THAT could be the perfectly circular trajectory illustrated. This may be what happens when there is extremely high margins on propellants and thruster lifetime. They do what they want without economizing.
Is the queue behind control centre for SpaceX catering?

Crew-2: Astronauts Safely Return to Earth at 10:33 p.m. EST

Thinking out loud here. What was going on with that 4th chute? Will NASA want/need a review before launching again? What would that mean for ops on station? I know that no-one has answered for these questions, so I guess what I'm asking is, Did that 4th chute look off nominal to anyone else for a significant period? I just didn't seem to want to inflate...
