well whose gonna tell the manufacturers of the A350 and 787 about this?

However carbon fiber parts on commercial jets that are subjected to repeated high levels of stress are subject (at least in theory!) to inspection and replacement on a schedule.

Also PRIOR to use in passenger aircraft they will usually TEST them a time or two! 😳


EDIT: I can't find it but somewhere out there in "internet-land" is a video of a 747 prototype having its wings stress-tested with massive hydraulic pistons. If you saw how far those wings could bend before they snap/fracture you would be amazed AND would never take off your seatbelt in a jet aircraft in-flight again. (you can be smashed to a pulp and the plane will literally be fine or close to it... beyond the dents in the cabin ceiling you made with your head that is!)

Yeah, I wouldn't be surprised to find out that pilots avoid turbulence due to what it does to the occupants, not the aircraft.
 
My mind is more blown by the fact that there were 18 bolts that held the sub closed, and they routinely only closed 17 of them because the 18th was at the top & harder to reach.

Stockton Rush must have been one damn convincible salesman. We're talking the level of politician.

One news anchor was pointing out that we know more about the space above us than our own space below us. Which is true.

The press is calling these victims "explorers". I don't look at them as being explorers. Lewis and Clark, now THEY were explorers. Neil Armstrong and Buzz Aldrin, they were explorers.

These five guys were not explorers, they simply paid a lot of cash and took a ride on a craft that even Disney would reject. But they are not explorers. A half a million for dad and son to commit hari-kari? Gee, thanks dad. Now AnandTech members, aren't you glad u have poor dads?
Yeah, ok, RIP.

PS. I wonder if this would have gotten so much attention if five black women living on welfare had been in that sub?

They weren't explorers, they were tourists.

Top Secret U.S. Navy System Heard Titan Implosion Days Ago

WASHINGTON—A top secret U.S. Navy acoustic detection system designed to spot enemy submarines first heard the Titan sub implosion hours after the submersible began its mission, officials involved in the search said...

WSJ News Exclusive | U.S. Navy Heard What It Believed Was Titan Implosion Days Ago

Underwater microphones designed to detect enemy submarines first heard the suspected implosion just hours after the submersible began its voyage.

SOSUS has been around for quite a while. I'm sure they made many improvements since I've retired.

I read that they reported their findings to the company and the coast guard when the vessel went missing Sunday. Of course they had no proof it was the missing vessel so the search had to go on for verification.
 
What I read was that the Navy folks were certain it was an implosion of an "underwater vessel/object" in that immediate area at nearly the exact moment communications with Titan were lost.

Of course there was no way to be absolutely positive it was the Titan at the time.

I'm sure testing and certification standards are a little bit more stringent than bicycle parts, so they probably don't have anything to worry about 😀

The "not worrying" part is more on the individual airline and their maintenance staff/policies than anything else. 😉

20 year old, meticulously maintained aircraft can be safer then poorly maintained nearly new ones!

150% of ultimate load to wing snap. The video that is easiest to find is usually the 777 test. They are also put through fatigue tests to 2x their maximum life time cycles.

We also know how to inspect carbon fiber when new and used. It's honestly amazing stuff, but it isn't a drop in replacement for metal and trying to design with it like you would Aluminum is going to create issues.

Don't you mean they refused to reveal the proof? 😉 Don't want to expose the full capabilities.

Also, the ocean is a noisy place, so findings need confirmation, especially when calling off the search would mean closing the door on the rare possibility that they would be found alive.

Nothing like listening to a cloud of shrimp popping. Sounds like the 4th of July on steroids.

They might have been pretty certain that's what it was, but could you imagine the circus that would ensue if it was later discovered that the noise was something else and the people were alive when the search was prematurely called off?

Or you were reading a site that likes that likes to exaggerate for effect. After the fact when they see the debris field, it's pretty easy to make a definitive call, but initially not so much:


A senior Navy official told CNN the Navy detected an acoustic signature consistent with an implosion on Sunday in the general area where the vessel was diving and lost communication with its mother ship.

The Navy immediately relayed that information to on-scene commanders leading the search effort, and it was used to narrow down the area of the search, the official said Thursday.

But the sound of the implosion was determined to be “not definitive,” the official said, and the multinational efforts to find the submersible continued as a search and rescue effort.

This whole thing kinda reminds of Patrick Boyle chastising crypto investors of "adhering to the proven investment strategy of investing first and performing due diligence after."
