Unless I'm mistaken, the subject article starts with the words "Submarine missing". The fact that the whole thing was jury rigged and double checked by nobody with certifications is enough to start pointing fingers at the engineers.
This isn't the company's first trip either. They've taken multiple trips down and have almost lost the submarine multiple times. This time they actually managed to lose it for good.
The reason people are mad at the company is because their negligence killed 4 people for no good reason.
