Comment on OceanGate’s ill-fated Titan sub relied on a hand-typed Excel spreadsheet

There were so many things relating to this incident that bewildered me. The titanium end caps were stuck on using glue, by hand. Also, while carbon fiber is great at handling tensile loads at 14 PSI, it’s not so great at handling compressive ones at 5500 PSI. For such a delicate mission, the whole thing seemed unprofessional in so many ways.

Supposedly the glued on titanium is the same thing the US Army does for their small Submarines, though I’m sure they found some way to cheap out/fuck up.

Probably were using expired glue, as Stockton Rush boasted about using discounted carbon fiber from Boeing that was past its shelf life for usage in airplanes.

I know of at least a couple maintenance shops that will give their expired composite materials to a mechanic school for students to use in class projects. This usage is actually a good idea, completely unlike using it to build a manned submersible.

Recycled parts? That’s simply being too dumb to be alive on this world. And I thought putting a wireless xbox controller for navigating the damn sub was dumb enough.

Frankly that controller was probably the most reliable part of the sub

Well, they did it just out in the open in some dusty warehouse. Comments I’ve read say that’s a pretty big deal.
