To add to the other poster, while the LES was jettisoned, in this case it seems that the booster failed to ignite, which allowed normal staging separation.

- rory096 8y agoThat's not right. The stage sep was the Soyuz strap-on boosters separating from the sustainer stage. It was already ignited.
- concerned_user 8y agoThere is no ignition on Soyuz, because they couldn't find a reliable way to ignite the engine when it was designed so second stage works from the start, it is the central part of the rocket, and 4 boosters around it. Second stage was shut down because of the problems with a booster separation.
- azernik 8y agoJust the tower, not the whole LES. See this video for an illustration of this rather exotic system: https://www.youtube.com/watch?v=QMUJ004Dr8Q https://www.youtube.com/watch?v=QMUJ004Dr8Q
