Way back when on June 20 EST after searches were launched, India Travel Times had, on an analysis of the data available, indicated the probability of Titan undergoing a sudden and massive implosion (inward collapse) at great depths. (SEE: Titanic expedition goes missing: A ray of hope from sounds of bang) Now videos taken by a Canadian robot that reached the floor on Thursday evening, June 22, has confirmed it. The fragments are lying scattered. Horizon Arctic's ROV robot found the debris 1600 ft from Titanic bow.

The submersible imploded at 500 metres above sea bed, if we go by our calculations. The water pressure it had to withstand at that point was 2,345 kg per sq inch. The hull was not built to take that, as per the court cases fought by concerned people at the time of building the sub and going by the details revealed in the cancellation of booking by at least one ocean expert.

St. JOHN'S (Newfoundland, Canada), June 23: At 1 hr 45 min after the dive proper began on Sunday morning off St John's, June 18, the Titan expedition to the Titanic carrying five passengers - submarine experts and business magnates included - lost communication with the Canadian support ship, Polar Prince, on the Atlantic surface anchored over the site of the century old wreckage. After four days of futile search by planes and ships sent by the US, Canada, UK and France, a robot finally dived to the bottom to discover the parts of Titan strewn around 1,600 feet from the Titanic following a catastrophic implosion.

Its scheduled duration for descent to the Titanic wreckage was 2 hrs 30 min total. Deducting 30 min for a slow dive as it nears the ocean bed, the actual time the vessel was to take in descending at normal speed for reaching the bed was 2 hrs. As it lost contact at 1 hr 45 min, the Titan, it can be assumed, faced the problem at a depth of approx 4,000 mts/120 min X 105 min (time covered) = 3,500 metres. Therefore, the mishap took place at a point 500 metres above the bottom. Or, taking into account the full duration of 2 hrs and 30 min at average speed, not giving a margin for slow dive, the disaster point is at: 4,000/150 min X 105 min = 2,800 metres depth, ie 1,200 metres above the ocean bed.

Therefore, the actual point of implosion or breakup is somewhere at a depth between 2,800 metres and 3,500 metres from the Atlantic surface. Or, somewhere between 500 metres and 1,200 metres above the ocean's bottom. Certainly it did not touch the ocean bed, which is 3,800 metres (12,467 feet) from the surface.

Below the surface, the water pressure increases by 1.96 kg per sq inch for every 10 feet of descent. That is, at the Titanic wreckage site on the Atlantic bed at 3,800 metres (12,467 feet) the pressure is 2,443 kg per sq inch. If the submersible imploded at 500 metres above sea bed, if we go by our calculations, the pressure it had to withstand was 2,345 kg per sq inch. The hull was not built for that, as per the court cases fought by concerned people at the time of manufacture and the subsequent cancellation of booking by at least one ocean expert.

Implosion at that level is so quick that it leaves no time to communicate, no time to even comprehend what is happening. Loss of communication is the communication!!! At that pressure, a human body becomes pulp in less than a second. In all probability, their end was not traumatic. No hypothermia, no hypercapnia, no decompression pangs!

Titan’s nose cone, view port, hull and other parts are strewn around. May have been carried apart by ocean currents, according to the data sent by the Canadian robot. Or, as it is thought, taking into account the duration of dive, the blast having taken place 500 metres above the bed, the debris would naturally have scattered all over.

A chronology of the disaster

On Sunday morning, June 18, the expedition was launched and the vessel was detached from the platform under sea at 10 am and the communication was snapped at 11.47 am. The actual journey was to be 2 hrs. It was expected back at surface at 6.10 pm. At 6.35 pm rescue operations started.

Titan was equipped with 96 hours of oxygen and life support.

It ws the Canadian P-3 aircraft that detected underwater sounds of banging in the search area every 30 minutes since Tuesday morning and continued on Thursday also which prompted the despatch of the robots. If that has discontinued? If that was false, what was it? There have not been any answers.

Canadian vessel Horizon Arctics' ROV robot reached Atlantic floor and started searching for the missing Titan at 4:26 PM Thursday. Later, French vessel L'Atalante deployed its ROV robot Victor 6000 at 5 PM. It could cut cables to free the submersible if it is stuck and put a hook so that the rescue ship on the surface can pull it up. The ROV has manipulating arms. And, the robot can work for 72 hrs.

The videos taken by the robot showed the debris scattered. The vessel's nose was found 1,600 feet from the Titanic bow.

The Polar Prince used a hydrophone to receive and translate the data.

Titan was 22-ft. long, 9.2-ft. wide and 8.3-ft. high and made of fibre and titanium. It weighed 10,500 kg and could carry a load of 680 kg. It could go to a depth of as 4,000 metres (13,123 feet) in the ocean. The Titanic wreckage is lying at a depth of 3,800 metres (12,467 feet).

The Titan was operated by the US-based company, OceanGate Expeditions. Its CEO Stockton Rush (one of the five passengers on board) had founded it in 2009 with a view to study the depths of oceans.

OceanGate has been operating undersea expedition to the Titanic wreck since 2021. Ticket costs $250,000 per person, according to the company's website.

Five people were arrested from a banquet hall in Sector 51 Noida on Thursday where they were called to hold a rave party in a trap laid by the animal rights group, PFA. They named Yadav but he was not present.

Betting through Dubai-based Mahadev Book in India is conducted through a countrywide network. Probes reveal that the online gambling is worth several millions and top politicians, officials and celebs have been beneficiaries.

TAILPIECE: Polling dates for some States are round the corner. Top politicians have begun their acrimonious debate who looted more, even as Mahadev is washing their dirty laundry in the open ghat. Come what may, one needs to seize power to amass "thy wretched pelf!" One simple question is, why else one should spend lakhs or crores to get elected! A question every Indian should ask to oneself at least once a day!

His inaction amounts to defeating the rights of the people of the State to welfare measures sought to be implemented through the Bills, the Kerala Government's petition submitted, while the State of Tamil Nadu remarked that its "Governor is acting as a political rival."

Tailpiece: Coming up back to back, the petitions in their totality seem to question the provision of Raj Bhavan, and not motives of a Governor as a person.

Hundreds of cars piled up behind the wreckage of crashes occurring one after other in backing up - continuous crashes to the rhythm of metallic clanks and bangs back to back. According to reports, some ops required 'Jaws of Life' to pull apart the mangled cars to save lives inside.

The pilots struggled with Emerson to thwart a shut-off as he reached for the T-handles (see pix). Later he admitted to police he had taken psychedelic mushrooms and had a "nervous breakdown."

Doctors reasoned how the incidence of heart attacks is spiking over time and advise the simple way to play safely is to take a break and rehydrate yourself.

But how come ten people, including children, die of cardiac arrest at Garba in 24 hours, and that at different places of Gujarat? Garba had been going on for six days, and every year it is celebrated.

The killing of a teacher in France by an Islamic radical last Friday is linked to the Israel-Hamas war in West Asia, say authorities.

Shocking news from the UK: Leading grocers have started bribing policemen with free food and drinks to persuade them to take action against shoplifters.

Shoplifting has risen by about 27 per cent in 10 major cities across the UK this year. The cost of retail crime last year was $2.15 billion. Besides, “We are seeing organised gangs threatening staff with weapons and emptying stores," Helen Dickinson, chief executive of the British Retail Consortium, said. Data shows that the police failed to respond to 73 per cent of serious retail crimes that included assault and abuse of workers, apart from shoplifting.

Isar Mohammad allegedly picked up a banana offered to Ganesh idol on Chaturthi at a makeshift temple in Delhi and consumed it.

Harris said hip-hop is “the ultimate American art form” that “shapes every aspect of American popular culture.” “Hip-hop culture is American culture,” she said in a talk at her official residence at the US Naval Observatory in Washington, D.C.

The social media had mixed reaction. There was much appreciation that she dances better than any VP in American history. But some called her "moves" as “cringe” while others did not like her pink pants - "pink pants don’t look good.” In fact, her ensembles have always been incongruous.

"Let’s see how the (Governor's) Vice-Chancellors are given salary." Mamata's extreme statements will put the Marxist Government in Kerala, which is also facing similar issues, to shame. Has she begun the countdown for a war on the streets?

It's true Mamata has come to see a conspiracy to demolish the established systems across the country, but lacks the ability to foresee what exactly is being pushed.

Brandishing a sword, Mahant Paramhans told reporters on Tuesday he himself will behead MK Stalin's son for his remarks against Sanatan Dharma in case nobody came forward to accept his offer he made in his video. Udhayanidhi reacted to the saint's Monday video, "I will speak more. I am the grandson of the artist who put his head on the rail track for Tamil Nadu."

Somanath elaborated, "I am an explorer. I explore the Moon. I explore the inner space. So it's a part of the journey of my life to explore both science and spirituality. So I visit many temples and I read many scriptures. So try to find the meaning of our existence and our journey in this cosmos. So it's a part of the culture that we are all built to explore, find out the inner self as well as outer self. So for the outer, I do science, for the inner I come to temples." (See videos)

Rao the mathematical legend had fathered the path-breaking Rao-Blackwell theorem, one of the most important theorems in mathematical statistics, at the age of 25. That brought him global fame. He is also famous for his Cramér-Rao Bound inequality theorem relating to quality of estimators in statistics which has had a profound bearing on applications of modern economics and several other diverse fields. Simply put, with the pioneering statistician computation became a tool to analyse even socio-economic challenges of modern times.

The alleged incident has received such a flash publicity that a standardised city's hugely middle class population will have second thoughts about eating outside for some time. Now everything on the table looks suspicious!

“All subjects directly connected to the people should be shifted to the State List. Particularly the subject of education. Only if this is done can cruel exams like NEET be abolished,” Stalin said. Education was moved from the State List to the Concurrent List with the 42nd Constitution Amendment made by the Central Government in 1976.

Decentralisation has been at the core of Tamil politics since the times of CN Annadurai. Stalin indicated there will be political changes in the offing.

TAILPIECE: While the Centre and the States are at loggerheads, it takes a different cognitive acumen to know that entrance tests are not the way for students' admission to courses.

Maruti is recalling 87,599 S-Presso and Eeco vehicles to inspect and possibly replace parts in the steering system. All reputed companies around the world do recall their products when a defect comes to light.

Meanwhile, a question arises why just in about a year so many accidents have taken place involving Mercedes sent to India while the car has won safety awards abroad? In most cases, the vehicle collided with divider, while manoeuvring a turn. Was there a split second delay in the steering system coming to a grip when at high speed? Did anybody in India bother to study a pattern in several of these accidents that took place one after other?

Former Tata Sons chairman Cyrus Mistry died when his Mercedes-Benz-SUV hit a divider in Gujarat. Cricketer Rishabh Pant's Mercedes-Benz-SUV rammed a divider in Uttarakhand and smashed. It went up in flames but he escaped with injuries. Brother of PM Narendra Modi, Prahlad Modi's Mercedes-Benz-SUV met with a similar accident in Mysuru. And many more.

• Experts blame violation of the Visual Flying Rules (VFR) for most of the chopper crashes in the mountains as the leading cause. VFR means fly only visually - because of the lack of navigation aids in remote areas or unreliability of GPS-like aids in hilly terrains or a remote manipulation of instruments in cases of sabotage - as the topography plays havoc especially in the monsoon (mid-June to September).
• Even when VFR is followed, most crashes occur due to CFIT (Controlled Flight into Terrain) - that is, everything else is OK but the aircraft collides with hills or trees hidden by the clouds. This also occurs mostly in the monsoon.
• On Tueday with Manang, the chopper was brand new, pilot was highly experienced. But it hit an 'invisible' tree and then crashed against a hillside. This CFIT occurred when the pilot tried to dodge patches of clouds even as he was following the VFR.
• Simply put, everyone knows flying in the hills during the monsoon is risky, but the companies want to make more money in any which case. This type of tragedy is very frequently invited in the Indian hill State of Uttarakhand as well, where pilots are even made to fly without the mandatory rest.
