Book 12 of 2026. Great read into the early life of Supermarine up to the Spitfire. Really enjoyed this, would have been cool to see the Type 327 and Type 316 bomber come to life!

Book 11 of 2026. Struggled with this one, maybe it was because I know a bit about space already, but found it hard to read.

Finally caved. I had a good run with one of my Aliexpress ones before this (7yrs), but the last one only lasted 1 yr. Should be good now 😁

Cool to see this in a ground test!

We've successfully completed performance testing of MIURA 5’s Flight Termination System (FTS). Using pyrotechnic devices, the test demonstrated the system’s ability to destroy the stage’s primary structure in the event of an in-flight anomaly.

This validation provides the evidence required to move forward with a major regulatory approval and brings MIURA 5 another step closer to operational readiness.

@RaulTorresPLD Awesome update, great progress! I am curious, what internal tools do you use for harmony and coms etc between teams and sites to move at this pace? Testing (epsilon3), cad, plm, work instructions etc etc.

First time seeing a Jumo 004 jet engine, this of course powered the ME 262 and the Arado Ar 234. Though this one has seen better days...

I knew the @Lilium test bed was saved and ended up in a museum, little did I know it would be the one I visited today!

October is a milestone-packed month for our MIURA 5 program, as we continue turning our launch system into a reality.

Here’s what’s taking shape across the program:

▪️Launcher qualification: MIURA 5 is undergoing system-level qualification, with three units manufactured.
▪️Industrial scale-up: Advancing our production capabilities to accelerate production and prepare for the next phase.
▪️Launch infrastructure: Progressing ground systems, civil works, and launch operations to build the foundations for liftoff.

The road to launch is taking shape. Every milestone advances MIURA 5 towards operational readiness.

Our Taiga team @Nord_Space is next level. Relentless beyond measure. Launch authorization seems imminent, a historic launch authorization for Canada no less 🤫 Testing Taiga on the new NightFox test cell at Area 66 before shipping out to make sure she still likes to sing, and boy does she ever. Next stop SLC-02 Pad 2A at our Atlantic Spaceport Complex in beautiful Newfoundland and Labrador, later this year.

To carry on with cool things, here is an ME 163 and its rocket engine, I tried to get a good picture of the engine injector.

Bluestreak. Unfortunately, could not get any closer.

[Iain Finer @fineri]

@Kedrskie Indeed a Polaris!

[Iain Finer @fineri]

@fin_ewt Same here! Yes, did see those in the corner and a Bluesteel. Though the RAF Museum in London has a Bluesteel you can get up and close to.
