An expert who raised concerns about the Titan submersible five years ago has told Sky News that his warnings were not heeded.
Back in 2018, William Kohnen had expressed fears that the vessel’s design and construction were not being tested by an independent third party.
In a letter to OceanGate – the company that owns the missing sub – he had warned that a “single negative event” could undo an “enviable” safety track record that spanned 40 years.

‘Why were you worried about Titan?’
On behalf of industry experts, Mr Kohnen had written: “Our apprehension is that the current experimental approach adopted by OceanGate could result in negative outcomes (from minor to catastrophic) that would have serious consequences for everyone in the industry.”
Speaking to Sky News after a “debris field” was found at the search site for Titan, Mr Kohnen said: “Father Neptune has absolutely no patience for humanity – if we get it wrong, we get it wrong and we pay the price.
“If we play in this game, we have to be absolutely sure of ourselves.
“We say we have rules and regulations – well they come because of mistakes, because of things we have learned, and we embody that in a process of certification.”
Mr Kohnen’s letter, from the Marine Technology Society, had been addressed to OceanGate’s CEO Stockton Rush, who was the sub’s pilot.
As well as lacking international safety certification, an old PlayStation controller is used to steer Titan, which Mr Rush defended as “super durable”.
OceanGate’s website adds: “The use [of] off-the-shelf components helped to streamline the construction and makes it simple to operate and replace parts in the field.”

‘Two friends of mine are gone’
Mr Kohnen had argued that it was critical for the company to spend additional time and expense on adhering to industry standards – but Mr Rush had claimed regulators were holding OceanGate back and stifling innovation.
“OceanGate was taking a strategy of ‘well, we intentionally break the rules because we can do it better and faster’,” Mr Kohnen said.
He explained: “Nobody has made a five-person submersible going 4,000m. Most of the submarines – there’s 10 submarines that will go 4,000m or deeper in the world – they are all certified and they tend to be three-people vessels with one pilot and two occupants for research.
“To do five passengers, it does push the envelope and you’ve got to do the numbers right.”
Mr Kohnen added that there are vessels capable of sending passengers to depths of 6,000m and 7,000m, but each went through a certification process.
“Submitting it to third-party review on a new design, we’re doing ourselves a favour and following the North Star in our industry,” he said.

Ex-Titan passenger: ‘It was not safe’
Arthur Loibl – who travelled aboard Titan as a passenger in 2021 – told Sky News that he felt the vessel “was not safe”, and “everybody was nervous” on the trip.
Communication with Titan was lost last Sunday during a voyage to the Titanic shipwreck in the North Atlantic off the coast of Canada.
The United Nations has condemned airdrops on Gaza, warning they risk killing the starving Palestinians they are intended to help.
Jordan, the United Arab Emirates, and Israel parachuted aid packages into the territory for the first time in months at the weekend amid claims a third of the population has not eaten for days.
But Philippe Lazzarini, commissioner-general for the UN Relief and Work Agency for Palestinian Refugees (UNRWA), has said they “will not reverse the deepening starvation” and often do more harm than good.
“They are expensive, inefficient & can even kill starving civilians,” he wrote in a statement on X.

There are several ways humanitarian agencies and international allies can deliver aid to regions in need – by land, by sea, or by air.
While parachuting in supply packages from planes may look impressive, airdrops are “fraught with problems”, Sky correspondent in Jordan Sally Lockwood says, and often used as a “desperate last resort”.
“Foreign nations know airdrops are a deeply flawed way of delivering aid,” she says.
“Palestinian sources tell us the aid that’s been dropped so far is not reaching the most vulnerable. They are an attempt to get something to a few – often viewed as a desperate last resort. Gaza is at that point.”

Military analyst Sean Bell says that delivering aid by air is ideally done when planes can land on a runway – but Gaza’s only landing strip in Rafah was shut down in 2021.
The alternative is “very dangerous”, he warns. “Aircraft flying relatively low and slow over a warzone isn’t very clever. When these parcels hit the ground, there’s a significant danger of them hitting people.”

Crucially, they can only deliver a fraction of what lorries can.
“The really big issue is aircraft can only deliver one truckload of aid. Gaza needs 500 truckloads a day, so it’s 0.2% of the daily need,” Bell adds.
They also risk falling into the wrong hands and ending up on the black market.
“Some of it has been looted by gangs and is on the black market already,” Lockwood says.

Why are they happening now?
Israel cut off all supplies to Gaza at the beginning of March, reopening some aid centres in May, but with restrictions they said were designed to stop goods being stolen by Hamas militants.
Israeli authorities control the only three border crossings to the strip: Kerem Shalom in the south, Crossing 147 in the centre, and Erez to the north.
Since the current conflict with Hamas began in October 2023, humanitarian agencies and world leaders have repeatedly accused Israel of not allowing enough deliveries through.
Mr Lazzarini says the UN has “the equivalent of 6,000 trucks” in neighbouring Jordan and Egypt “waiting for the green light to get into Gaza”.
Israel says it has commissioned a “one-week scale-up of aid”, having conducted its own airdrops on Saturday.
In a statement over the weekend, the Israeli Defence Forces said it will work with the UN and other aid organisations to ensure aid is delivered but no more details were given.
Meanwhile on Sunday, it began daily 10-hour pauses in fighting in three areas of Gaza to address the deteriorating humanitarian situation.

Sky’s Sally Lockwood on the runway in Jordan ahead of Gaza aid airdrop
What are in the airdrops and who is behind them?
Air packages are largely being delivered by C-130 planes. Jordan is reported to be using 10 and the UAE eight.
They can carry eight pallets of goods each, weighing around eight tonnes in total, according to Lockwood, who is on the runway at Jordan’s King Abdullah II airbase.
There are no medical supplies in the packages, she says, only dried food, rice, flour, and baby formula.
Prime Minister Sir Keir Starmer has said the UK will help with airdrops – but no British aircraft have been seen in Jordan so far.
He will discuss the matter with US President Donald Trump during talks in Scotland on Monday.
The RAF delivered 110 tonnes of aid across 10 drops last year as part of a Jordanian-led international coalition – but it is not clear what level of support will be offered this time.
Israel has agreed to support a “one-week scale-up of aid” in Gaza – but the United Nations has warned more action is needed to “stave off famine and a catastrophic health crisis”.
UN aid chief Tom Fletcher made the remarks as Israel began limited pauses in fighting across three areas of Gaza for 10 hours a day to address the worsening humanitarian situation.

On Saturday, reports referencing US government data said there was no evidence Hamashad stolen aid from UN agencies.
Images of emaciated Palestinian children have led to widespread criticism of Israel’s actions in Gaza, including by allies who are calling for an end to the war.
Mr Fletcher said one in three people in Gaza “hasn’t eaten for days” and “children are wasting away”.
He added: “We welcome Israel’s decision to support a one-week scale-up of aid, including lifting customs barriers on food, medicine and fuel from Egypt and the reported designation of secure routes for UN humanitarian convoys.

The Israel Defence Forces said yesterday that it is halting military operations in Muwasi, Deir al Balah and Gaza City daily from 10am to 8pm local time (8am to 6pm UK time) until further notice.
Combat operations have continued outside of this 10-hour window. Health officials in Gaza said Israeli strikes killed at least 41 Palestinians overnight into Sunday morning, including 26 seeking aid.
In a statement, the IDF said it would also establish secure routes to help the UN and aid agencies deliver food and other supplies.

Israel’s announcement of what it calls a “tactical pause” in fighting comes after it resumed airdrops of aid into Gaza.
While the IDF reiterated claims there is “no starvation” in the territory, it said the airdrops would include “seven pallets of aid containing flour, sugar and canned food to be provided by international organisations”.
Palestinian sources confirmed that aid had begun dropping in northern parts of the territory.

Sabreen Hasson, a Palestinian mother who travelled to an aid point near the Zikim crossing to collect supplies, said: “I came to get flour for my children because they have not tasted flour for more than a week, and thank God, God provided me with a kilo of rice with difficulty.”
But Samira Yahda, who was in Zawaida in central Gaza, said: “We saw the planes, but we didn’t see what they dropped… they said trucks would pass, but we didn’t see the trucks.”
Another Palestinian told the AP news agency that some people feared going out and having a box of aid fall on their children.
Downing Street said Sir Keir will raise “what more can be done to secure the ceasefire [in the Middle East] urgently”, during the meeting at the US president’s Turnberry golf course in Ayrshire.
Reports also suggest the prime minister is planning to interrupt the summer recess and recall his cabinet to discuss the crisis on Tuesday.
Talks in Qatar over a ceasefire ended on Thursday after the US and Israel withdrew their negotiating teams.

Bob Geldof: ‘Israeli authorities are lying’
Mr Trump blamed Hamas for the collapse of negotiations as he left the US for Scotland, saying the militant group “didn’t want to make a deal… they want to die”.
Meanwhile the exiled head of Hamas in Gaza, Khalil al Hayya, has warned ceasefire negotiations with Israel were “meaningless under continued blockade and starvation”.
In a recorded speech, he added: “The immediate and dignified delivery of food and medicine to our people is the only serious and genuine indication of whether continuing the negotiations is worthwhile.”

While the IDF reiterated claims there is “no starvation” in Gaza, it said the airdrops would include “seven pallets of aid containing flour, sugar and canned food to be provided by international organisations”.
Reports suggest aid has already been dropped into Gaza, with some injured after fighting broke out.
He told Sky News: “This month, up to now, 1,000 children or 1,000 people have died of starvation. I’m really not interested in what either of these sides are saying.”

Malnourished girl: ‘The war changed me’
Airdrops ‘expensive and inefficient’
It comes as the Hamas-run health ministry in Gaza said as of Saturday, 127 people have died from malnutrition-related causes, including 85 children.
They include a five-month-old girl who weighed less than when she was born, with a doctor at Nasser Hospital describing it as a case of “severe, severe starvation”.
Health workers have also been weakened by hunger, with some putting themselves on IV drips so they can keep treating badly malnourished patients.

Aid waiting to be distributed in Gaza
On Friday, Israel said it would allow foreign countries to airdrop aid into Gaza – but the UN Relief and Works Agency (UNRWA) has warned this will not reverse “deepening starvation”.
UNRWA head Philippe Lazzarini described the method as “expensive” and “inefficient”, adding: “It is a distraction and screensmoke. A manmade hunger can only be addressed by political will.
“Lift the siege, open the gates and guarantee safe movements and dignified access to people in need.”
UNRWA has the equivalent of 6,000 trucks in Jordan and Egypt waiting for permission to enter Gaza, he added.

PM says UK will help drop aid to Gaza
MSF, also known as Doctors Without Borders, warned on Friday that 25% of young children and pregnant women in Gaza are now malnourished, and said the lack of food and water on the ground was “unconscionable”.
The UN also estimates Israeli forces have killed more than 1,000 people seeking food, the majority near the militarised distribution sites of the US-backed aid distribution scheme run by the Gaza Humanitarian Foundation.
In a statement on Friday, the IDF had said it “categorically rejects the claims of intentional harm to civilians”, and reports of incidents at aid distribution sites were “under examination”.
The Gaza Humanitarian Foundation (GHF) has also previously disputed these deaths were connected with its organisation’s operations, with director Johnnie Moore telling Sky News: “We just want to feed Gazans. That’s the only thing that we want to do.”
