@CalumDouglas1 Unfortunately there’s a lot of “safety” culture that is that way - “I’ve ticked my boxes!”

This is funny, the worthlessness of PAT testing. The welder has been awarded a “passed electronic safety” sticker.
It’s been fitted (wrongly) with a domestic 13amp plug… it’s supposed to have a 6-50P industrial socket rated to 50amps, and at 230v it draws 30A if you push your foot to the floor and needs 15amps to just safely supply the min rated duty cycle.
But this machine is tested safe ! Look observe the sticker ! 🙄

@gak_pdx As a demonstration of how available standard bearings can be, my Dad’s steam wagon (designed in 1921) some of the original Timken bearings it has are still in the catalog with the same part number!
English
You hear this, but 9 times out of 10, the real story is that some engineer designed around a special bullshit part where the lead time/quantity when buying at scale is no big deal. Fine for the machine builder, but unless they denote those parts, stock the hell out of them, and stay in business for perpetuity, this situation will *always* bone end users somewhere down the line.
With a handful of *very* special exemptions (you cured cancer, or broke light speed, or figured out time travel), if you can’t work around the Timken stock catalog, you have a skills issue.

Customer told me that the bearings on a precision assembly we are rebuilding for him have a 40 week lead. 40 weeks?! If the bearings fail and the line is down for 40 weeks, he will lose his job. We need new ideas; critical infrastructure can’t be held hostage like this.

@edwards345 @michaelnicollsx It’s wild when you look at rate. In a little less than 8 years, I’ve already been part of >90% of company launches!

600 landings in just over 10 years - not a bad start!
Well done SpaceX and Falcon! 👏👏

Journo here. If you ever want to feel filthy stupid when in a jail cell, get up after you’re done chatting and try and open the door. From the inside. Lads, transpires jail cell doors don’t open from the inside

@DJSnM @Dylan_Morri If you work consistently in one system, you get more feel for what’s going on. In a previous job, tensile tests were run in the units that were requested. I changed it so we ran the tests consistently but converted results to whatever was requested. Cut error rates dramatically!
English
@Dylan_Morri Indeed, every engineer should be able to read specs in various units. As long as the designs they produce are consistent.
English
Hot take, engineers should be units agnostic
Afshawn Lotfi@afshawnl
i've never met a great engineer who didn't have a strong opinion about units. also if you use lbf i hate you

@Aviation_Intel How much of a history of repairing battle damaged pressurized cabin aircraft is there? Obviously this is a different problem to repairing a flak damaged B17.

Battle Damaged KC-135 Seen Covered In Shrapnel Patches
A KC-135 damaged in an Iranian strike has made its way to RAF Mildenhall in the UK thanks to field repairs.

@BillJensen67508 @airandspace Nothing could be further from the truth. I doubt any of us involved with Crew 9 feel that we didn’t get enough credit or thanks.
English
@airandspace It's nice that these two humans thanked SpaceX for bringing them back home. Oh, that's right, they didn't. What classless ingrates. 🤦♂️

Last night, the Museum’s 2026 Michael Collins Trophy for Current Achievement was awarded to the Boeing Starliner Flight Test Crew.
Astronauts Sunita “Suni” Williams and Barry “Butch” Wilmore’s extensive spaceflight experience prepared them to not just adapt but excel with personal strength, grace, and competence when their eight-day mission turned into one that lasted more than nine months. Watch the featured video now.

@McCainJack Ummm, don’t we want criminals to film themselves doing crimes?

@heatloss1986 Given the advantage of 2 crew to split the workload, and the emissions tracking Serrate/Perfectos, seems like a contemporary AI. Mk X (SCR 720) equipped Mosquito NF.30 was probably still a more effective option. The Nachtjagd was certainly terrified of them.

Had single seat Hellcats been deployed over Europe to assist the British night raids or had the USAAF adopted the AN/APS-6 on escort fighters, the German night fighters would have been shredded. It's not even close.
Range, reliability, usability, and weight were all in our favor.
English
I cannot underscore enough how much people overlook the F6F-3N/5N as a night fighter. Much is made of the German night fighters, but they shot only bombers and were vulnerable to defensive fire.
Single seat Hellcats went hunting for fighters too.

@EODHappyCaptain I’m sorry to hear about your grandfather.
This definitely seems like it’s in the “sad but not tragic” realm - I think that’s a good way of distinguishing between circumstances.
English
My grandpa passed away a couple of weeks ago and I have been traveling. He was an incredibly kind man who taught me a lot. I never once heard him yell.
I know the comments will be filled with condolences, but here’s the thing: he passed away at 89 years old in his sleep. Surrounded by family. In his own home.
I’ve lost friends who weren’t so lucky; whose lives were cut short from war and many times the aftermath of war.
I’m so happy I had the chance to really know my grandfather. I’m happy he taught the value of kindness. As sad as I am that the world is without him, I can’t help but hope that someday I get to go out the same way: surrounded by family at an old age.

@KennethCassel The power move is to reply all with “thanks for the assistance! 🐟”

an engineer on our team inquired about a new piece of a equipment from a manufacturer and they accidentally included him on the internal email chain where they said to be careful because we seemed fishy lmao

@punky_01 @clark_aviation It’s post-war, as you can see the serial number painted under the wing.

@clark_aviation No nose turret was to be seen and extra antenna was to be seen.

It's been a while since I first posted this remarkable image. An RAF Avro Lancaster bomber performing a very low pass on just one engine. This feat was a popular 'party piece' for a few very skilled pilots, together with a very deft flight engineer!

@connorlandgraf @pronounced_kyle @Astranis Just about every fairing already gets recovered and reflown! You can see the weathering on the fairing in the picture above.

@pronounced_kyle @Astranis If you could recover the second stage fairing with the Astranis logo, that would be the most epic office decoration.

When you buy a SpaceX rocket, they let you watch the launch at one of their buildings at Cape Canaveral.
One small detail that stuck with me: their building has a kid's room! It ruled. Stocked with snacks, Bluey playing on the TV...
SpaceX is a pro-human company, and it shows.

Incredibly disappointing that Southern California is getting the cold shoulder on this tour. I guess UP don’t want more cool shots of Big Boy 4014 muscling through a canyon in the Mojave Desert. Sigh.

@thejackbeyer Yeah, that is very disappointing! I had thought that particularly as it spent decades in Pomona that SoCal would be on the itinerary again!
