After a few days of the Titan disappearance announcement Titan members lost their lives due to internal explosion.

Now, the rescue efforts are turned towards understanding what caused the accident.

According to Rear Admiral John Mauger, what they found was consistent with a “catastrophic implosion”.

After a long time search they’ve found patches of debris, one containing Titan’s tail cone and the other its landing frame.

Why did the Titan implode ?

The pattern of the debris shows that at some point in the Titan’s journey there was a leak.

It was so deep in the sea by then that the amount of water above it would have been equivalent to the weight of the Eiffel Tower.

How will the investigation proceed?

According to Ryan Ramsey, former submarine captain in Britain’s Royal Navy.

“There is no black box, so you are not going to be able to track the last movements of the vessel itself,” 

“But otherwise the process of investigation is not dissimilar to that of an airplane crash.”

Mentioning that the Titan’s body is in small pieces.

Remotely operated vehicles are collecting the pieces in the darkness of the deep sea.

Is it true that no safety test was there ?

Most merchant vessels have to be certified – which is a process whereby an external body inspects it to see if certain standards are met. 

This was not the case with OceanGate. The firm said that was because it was an experimental vessel. 

Prof David Andrews of University College London said:

“That might be fine if you are an exploratory craft pushing the boundaries for research.

“BUT once you start earning money by taking passengers then eyebrows start being raised.”

Who will lead the investigation ?

It is important to focus on the fact that the incident took place in a remote part of the ocean involving people of many different nationalities.

At this stage, it is unclear which agency will lead the investigation as there is no protocol for such incidents.

But since the US coast guard has played a leading role in the operation so far, it is likely to continue to play an important part.
