Titanic tourist sub goes missing sparking search

So this brings up a question - how many full-depth test dives were conducted before the repair/replacement of the carbon-fiber hull? From Wikipedia it sounds like they did 13 dives on Titanic afterwards (not sure if those were all dives that made it to the wreck or if they count aborted dives). If the hull showed significant fatigue after a limited number of dives, that should have been a giant red flag.

I think that we can all agree that there are too many guesses, assumptions, opinions, feelings, hunches, hearsay, second hand intel, 5 years old information, Wikipedia stuff (since when is it considered flawless) and very few proven and updated facts around here to really determine what happened. Only the investigation from the Canadian authorities will give us that.

Would the scan of the carbon fiber have picked up the screw holes where they screwed the monitor into the hull?

Look more closely at the picture of the meme.

It appears to be screwed into the insulation behind the perforated sheet that holds the insulation in place.

Here you can read a recent scientific paper describing the mechanics of implosion of a spherical bathyscaphe and the resulting shock wave propagating around and damaging other structures:

In this folder you find also a number of PDF documents related to the Titan submersible and providing info and technical specs.

Here is a Vimeo link to a video made by the BBC on a previous Titan trip to the Titanic.

In some of the video on the wreck, there are 2 green dots...
Is there a laser range finder?
Or just a laser to help show the direction

I have a carbon fiber mountain bike and I sometimes wonder how many years of punishment can that frame can take

For a long time, as long as you don’t get it run over by a car.

Under the floor there doesn’t seem to be enough space for tanks and/or rebreather equipment. Looks like a gaming console under the floor.

OceanGate CEO once said Titan sub's hull was made with carbon fiber from Boeing that was past its airplane shelf life, would-be passenger says

Arnie Weissmann said OceanGate CEO Stockton Rush told him he sourced the Titan's carbon fiber, which was too old "for use in airplanes," from Boeing.

As if it wasn’t bad enough that he used carbon fiber now someone is saying that the material was bought at a discount from Boeing because the use by date had come and gone? WTF was this guy and his enablers thinking?

I remember when Boeing surplused a bunch of carbon fiber.

According to Wikipedia, ISO (metric), NPT and UTS (UNF, UNC) are 60°.
Withworth and British Standard (BS) are 55°:

Thread angle - Wikipedia

en.wikipedia.org

We usually refer to this as a Gas thread.
The DIN thread for regulators is G 5/8" BSP, so it has a 55° angle.

I apologize for the wrong information I posted earlier.
I corrected my previous post.

Sorry, I just reread that and realize the BS was a poor choice for several reasons.

That BS wasn’t for British standard, it was meant as bovine excrement
