@rob_sv650s @Jordan_W_Taylor His autobiography “Not much of an engineer” is well worth a read.

@Jordan_W_Taylor Stanley Hooker, who worked for RR on developing the Merlin throughout WW2 was knighted for getting the RB211 into succesful production.

The Rolls-Royce RB211 was a perfect athlete. A 70s technological marvel, this is the jet that almost broke Rolls-Royce, driving it to near bankruptcy. A broad menu of technological firsts were attempted in this program, including carbon-fibre fan blades (which Rolls-Royce subsequently backed away from). The RB211's design legacy was the fabulously successful Trent family of engines that has made RR the aerospace colossus it is today.
Not bad for a half-century bet!
But the biggest hidden design legacy of RB211's ambition is the addition of a 3rd spool inside the engine: A shaft inside a shaft inside a shaft, each powered by, and powering, a different part of the turbofan. The design & manufacturing difficulties of this architecture, still unique to Rolls-Royce, were legion, but it paid off: Not only does a third shaft allow you to run the big fan from its own dedicated low-speed, low-pressure turbine stages, but it also adds impressive modularity to the engine design. This allowed RR to scale-up and optimize the Trent family for new airliners with impressive agility, which in turn let them successfully slug it out with their far larger American competitor, General Electric.
Modularity matters.

@OnlyWaifu It could use a rudimentary quest log. Not way marks or map pointers, maybe just a transcription of NPC encounters to refer back to.

@matoxley Looks like a local council repair , one man working, one leaning on a shovel and 10 managers watching.

@andrewmccalip The ‘Steam’ GWR museum in Swindon is worth a visit. Same story, raw materials in one end, rolling stock out of the other.
English

Harland & Wolff didn't build the Titanic the way we'd build anything now. There was no supply chain. The supply chain was the yard.
Fifteen thousand workers at one address. Naval architects drawing lines upstairs. Loftmen chalking those same lines full-scale on the mould loft floor. Rivet gangs working 200 feet up on staging that swayed in the wind. Boilermakers rolling steel plate nearly an inch thick. Three million rivets, set by hand and pneumatic hammer.
The infrastructure to make it possible was its own kind of mad. A gantry 228 feet tall and 840 feet long. Overhead cranes cycling plates and frames through the yard like inventory on a factory floor.
And then the part that gets me, the finishing trades worked in the same yard as the heavy steel men. Cabinet makers shaping first-class paneling. French polishers finishing mahogany like they were building a concert piano. Pattern makers carving wooden forms so molten iron could be poured into exact shapes. Blacksmiths forging brackets the same day they were needed. Electricians wiring thousands of lights into a hull that was still being riveted together.
No vendors. No procurement lag. No abstraction between drawing something and making it. Just one place that could turn raw steel and timber into an ocean liner, end to end, because every trade was under the same gantry.
We don't build like that anymore.

@Kev_opati @j0ker937 @grok The drogue has a small air powered generator that illuminates a set of small lights around the rim of the basket.

The way CASINO ROYALE changed Bond films will never not be revolutionary.
From the very first moments, it’s clear this isn’t the same 007 from the previous movies.
This Bond is brutal, smarter, more grounded, cold blooded.

Name the greatest opening scene in a movie or series.

@SpawnYaardReply I had to go back and recover my blood echoes/runes/souls but the boss was gone.

@SpawnYaardReply I was sailing through NG+ til I got back to these guys.
