Notice - I'm not arguing. Yes, discussing the Shuttle is a deviation and I've acknowledged that. Discussing me is an even bigger deviation and I won't be discussing that topic any further.
However, I did think that there were some similarities between what happened with Challenger and this recent Soyuz incident - with wildly different outcomes, of course.
Comparing and contrasting escape systems, types of failure and investigating those failures has been brought into this topic by the news. So IMHO the Challenger failure stuff was on-topic but it was drifting further off with the wider shuttle stuff.However, I did think that there were some similarities between what happened with Challenger and this recent Soyuz incident - with wildly different outcomes, of course.
In general I try to respect view thread starter's view with regard to what is in scope or what is off topic, which in this case happens to be you.
NASA seem committed to ongoing collaborate with Soyuz and ISS.

First hand account by Nick Hague, nothing unexpected but interesting nonetheless.

Interestingly, a Soyuz booster was used last night to launch a Russian military satellite (Cosmos 2528) from the Plesetsk Cosmodrome. I'm not sure if it's the same version of the booster used for manned Soyuz missions.
There's an article onNASASpaceflight about how there are several Soyuz launches coming up, including at least one of the same model which failed, which will be used to recertify it for manned flighthttps://www.nasaspaceflight.com/2018/10/nasa-rosco...

Roscosmos have released a video of the launch:

Keep an eye on the left hand booster after 1.20 minutes in.
It's pretty clear that the top of the booster failed to detach upon separation; So the pointy nose pivoted inwards and pierced the main rocket's tank.

... and watch it at 1/4 speed to see what actually happens, otherwise it unfolds too quickly to really see.https://www.youtube.com/watch?v=CrzlMTRVt_I

Good explanation by Scott Manley -

A bent pin stopped the sensor for activating - which stopped oxygen venting - which stopped the tip of the strap on booster pivoting away from the center core stage.
The question has to be - how did the pin get bent in the first place. It looks like it was due to sloppy and poor assembly.
