Yeah, definitely a planned LES test, with US astronauts on it.

It was an unscheduled rapid disassembly of the rocket, which led to an impromptu test of the LES. Unfortunately, it happened to shorten the mission somewhat, skipping the "go to ISS" stage between "send astronauts to space" and "take astronauts back to Earth".

With the 90km apogee they also skipped the "send astronauts to space" part.

The change of plans meant they weren't going to stay in space for long anyway. Might as well turn back early to avoid traffic on the return leg of the journey.

Apollo had an very successful LES test as the test rocket used for the test RUD and the LES worked flawlessly. 

Was not the LES tower ejected just before booster separation? 
Think that was an weird time to do it rater than waiting to just after separation.

so far it's been highly successful at delivering pork to the locals

They encountered severe difficulty in finding any locals.

Most of the pork ended up in Kazan, despite being haram. Yay secularism?

Booster separation is perfect time for RUD.

On a separate note, the lack of a movie theater in Tsiolkovsky is not surprising - big screen profit margins in Russia are plummeting.

Soyuz-7 hype!

AFAIK, rapid reuse is planned for stage 1 and spaceship.

It was supposed to be a meme.

How are they planning on recovering the first stage?

Not on this design, they aren’t. That looks like an RD-180, which reacts badly to being throttled down. Something radically different is required for SpaceX-style first-stage reuse they’re promising.

Yes, on this design, but not SpaceX-style. Their CEO said in an interview that they’re looking into hypersonic chutes and small dedicated landing engines.

Anyway, it’s much more interesting to me than Roscosmos stuff. Big projects like Vostochny, Angara, Federatsia, etc. have a habit of being delayed 2 years every 2 years or so. People in charge of these projects regularly get fired, jailed or found dead from unknown causes. It’s all so sketchy and dodgy that I don’t really expect any of those things to be completed in foreseeable future. On the other hand, private company like S7 Space is a business; it’ll either make their rockets work in reasonable time or go broke. Much more interesting to watch.

Hmm... Have you ever read through "Eyes Turned Skyward"? The author had an idea (a rather clever and elegant one, at that) to use a pair of essentially vernier engines for both the boost and landing phases, with the main engines used only during the boost. Perhaps they could do something similar? It's added complexity, yes, but it's also not going to require development of a new, large-scale, deep-throttling engine... just a smaller engine of the right thrust class to handle the nearly empty stage at, mmm... 2:1 TWR? Maybe less.

Lateral engines? That’s the approach from Energiya boosters, and it has serious problems - without accounting for Sea Launch.

I’m not the author, but I had that idea. Soviet military missiles tend to have powerful verniers that are entirely independent from main engines. I’ve ran around with the idea of Falconizing the Soyuz-2.1v (which has an RD-0110 wrapped around the main NK-33/RD-193) about half a year back.
