== It fell apart, and/or blew up.

* Especially SpaceX

@davidtheeviloverlord @catsalad
Additionally, Engine Rich Combustion.*
== Engine(s) are eating themselves. This is generally not a desired outcome.

* Most often seen on SpaceX's Starship test flights - look for greenish flames.

@rabidchaos @catsalad

See also: Infrastructure Geographical Relocation*

== Infrastructure has exploded and scattered itself over a wide area.

*Most often seen at SpaceX launch facilities due to removal of "unnecessary" features like cooling ponds.

@rabidchaos @davidtheeviloverlord @catsalad You got to hand it to SpaceX for their innovative problem solving.... engines that self consume? We can fix that.... ADD MOAR ENGINES
@Syulang @rabidchaos @davidtheeviloverlord This sounds like my strategy in Kerbal Space Program.
@catsalad @rabidchaos @davidtheeviloverlord To be fair, KSP seems to be a better lesson in rocketry than the K-hole, going by Elon's engineering decisions.
@davidtheeviloverlord @catsalad But SpaceY also had "engine rich exhaust".
@catsalad flora needs some percussive maintenance 🥺👉👈
@catsalad I learned "percussive maintenance" from Star Trek Prodigy
@catsalad my favorite engineerism is prolly "Lithobraking", AKA crashing into the ground which, to be fair, is a very effective means of slowing down your descent.

@Owlor I love it! 😹

According to Jonathan McDowell, "Lithobraking reduces the apoapsis height to zero instantly, but with the unfortunate side effect that the spacecraft does not survive. Originally a whimsical euphemism, but increasingly a standard term."

https://en.wikipedia.org/wiki/Lithobraking

Lithobraking - Wikipedia

@Owlor @catsalad very much viable in KSP. Unless you try it while landing in a liquid (landing on a liquid in KSP is more dangerous for crew than landing on solid ground if your craft is pointing retrograde, since although parts will only break on contact with liquid with a higher impact velocity, parts breaking on liquid do not slow down the rest of the craft, leading the entire craft getting apparently eaten upon contact, whereas if landing on solid ground only your engines and lower tanks will be destroyed and your crew capsule will survive - of course if you are in a nosedive and cant flip the craft back around, firstly you are probably going too fast to survive and dont have the ability to slow down enough to deploy parachutes, but in the very specific case where your parachutes are deployed but are at the bottom of the craft then deploying them over a liquid is a better bet).
@Owlor one of the Mars probes used controlled lithobraking, with airbags so it bounced to a stop
@catsalad "Thermal Excursion" == it overheated and caught fire
@signaturefish @catsalad "Thermal Runaway" == it continued heating up when it shouldn't. might trip a protection system and shut down (prusa brand 3d printers do this if the heatbed or hotend rise in temperature to more than ~20 kelvin above their set temperature if said temperature is sufficiently high (so that it doesnt trip when setting the printer to cool down) and start cooling down and abort any ongoing print) or might just catch fire.

@catsalad
Love those.

Room for another?

Aqueous Impairment
== It got wet

@robchapman @catsalad

Enviromentally driven impedance reduction

@catsalad is there a poster of this? I could imagine it would have a large market…
@catsalad I love Rapid Unscheduled Disassembly = it blew up in rocket speak.
@catsalad Ohm's second law; it works better if you plug it in.
@catsalad PEBKAC == Problem exists between keyboard and chair
ID10T error == The user is an idiot (works best if not written down)
@ComPod
Also known as PICNIC:
Problem In Chair Not In Computer
@catsalad
@catsalad I think your post is getting formatted weird, the irl explanation is appearing a line below the engineer speech but just randomly word wrap style
@catsalad aerosol escape: it let out the magic smoke 💻💨

@catsalad

Fabulous engineering-speak translations!! My favourite is:
"Percussive Maintenance
⩵ It was hit with a hammer⁠🔨" 😃

@catsalad I’m guessing you found another bug with your edits -for readability- being earlier than your original post?
@boiert I'm a bit of a bug enthusiast.
🐜🦗🪳🐞🪲🪰🦟
@catsalad Ahhhh a collector 😉
@catsalad Don't forget Magic Smoke™ (the thing that keeps electronic components running, and they fail the moment the smoke leaves the enclosure)
@catsalad Prompt Plating Event: Blew up so good it plated the copper all over the inside of the enclosure.
@AMS @catsalad I’ve seen this one! We had a manufacturer rep coming out to diagnose an issue with a compressor and the junction box on the side of the motor just shot sparks everywhere, guy goes, “Well, there’s yer problem” and walks out of the engine room. Don’t bend your cables past the minimum bend radius when tucking them back in, folks. You can break strands and create a high-R connection that eventually liquifies and explodes under starting current.

@catsalad
I've relied heavily over the years on using the technique of:

•Impact adjustment

=Hit it with a hammer

@catsalad don't forget the Random unplanned disassembly
@catsalad "high velocity remodeling" - we threw it out the window in frustration
@catsalad "binary fingercount of 132"
@catsalad

Hardware error – something physical failed
Software error – something logical failed
Meatware error – something human failed
@catsalad rapid unscheduled disassembly

@catsalad Two that I’ve been required to use at past jobs:

fire -> thermal event
bomb threat -> suspicious package

@catsalad unscheduled cloud integration == hack & leak, or datacenter fire
@nintegge @catsalad surprise distributed backup == leak
@catsalad I love "percussive Maintenance", didn't know that one yet :D

@catsalad Hey! You forgot some.

* Unscheduled excursion
= It blew up

* Unwarranted relocation
= It blew up

@catsalad Many years ago I worked on a linear motion system. I considered the use of ball screws to reduce friction in the system.

The catalog explicitly stated not to remove the nut (that held the ball bearings and did the moving) from the screw or "auto-disassembly will result". ==> all the ball bearings will fall out.

@catsalad Digital compression (pressing something with a finger)
@catsalad I had the most difficult time trying to explain ANALOG vs. DIGITAL to my 80yo neighbor. All she could gleen from my analogies was that digital stuff had more capabilities. Even describing Dorothy's Yellow Brick Road vs. an asphalt road didn't help.
