Tourist submarine exploring Titanic wreckage disappears in Atlantic Ocean

Showed the vid of them installing the ring to a buddy that does a lot of aerospace carbon work. He said the same thing about not enough space for the glue. The surfaces should have been concave. There should have also been primer on the TI ring. They also should have bead blasted the bonding surfaces on the ring.

...and put the entire thing under vacuum to remove the possibility of air bubbles while the adhesive sets.
 
Keep in mind though that most composite bonds are under tension where the bond between composite and fitting is critical for overall function. These were not. All the bond really has to do is seal and hold the end bells in place. You could almost not use any glue at all since pressure with push the bells onto the tube.
 
Did this titanium tube in the center of the carbon fiber layup have flanges on the ends like a cable spool or were the flanges glued on after the fact? I kept thinking this titanium tube looked like a cable spool and had flanges on the ends that were part of the main tube. Is that now how it was made?
 
I figured the 5" carbon wrap was so that they could machine down a thick piece of titanium pipe to make it look like a cable spool and then wrap the center in lightweight carbon fiber and resin to keep the strength they machined out without the extra weight?

No. Just flush like a PVC drain pipe.

Might have been a better approach.
 
This guy was on the second dive. "Expect to hear loud noises"

"fireworks" "small caliber gunshots"

 
I watch this last night. It has some details on the building the sub. What I found a little bit notable about it was they appear to have used a steel sphere. It also appears that the hatch could not be opened from the inside. Possibly not be able to open until it was on ship.

After all the furor about scaffolding tubes, found a picture of them and IMO they are new schedule 40 or 80 steel pipe, not scaffolding tube, from this video:
