Despite the largest search in aviation history, the plane has not been found.

Kuala Lumpur said in a statement it "wishes to update that the deep-sea search for (the) missing wreckage of Malaysia Airlines Flight MH370 will be resuming on 30 December 2025".


Maritime exploration firm Ocean Infinity will be conducting the search "in (a) targeted area assessed to have the highest probability of locating the aircraft", the ministry said.

The latest search in the southern Indian Ocean was suspended in April as it was "not the season".

It was conducted on the "no find, no fee" principle as Ocean Infinity's previous search, with the government only paying out if the firm finds the aircraft.

Ocean Infinity, based in Britain and the United States, led an unsuccessful hunt in 2018, before agreeing to launch a new search this year.

An initial Australia-led search covered 120,000 square kilometres (46,300 square miles) in the Indian Ocean over three years but found hardly any trace of the plane other than a few pieces of debris.

The ministry said the latest development underscores its commitment in "providing closure to the families affected by the tragedy".

Relatives of the victims had voiced hope in February that a new search could finally bring some answers.

When contacted by AFP, relatives of victims were not immediately available for comment.


Aviation mystery

The plane's disappearance has long been the subject of theories -- ranging from the credible to outlandish -- including that veteran pilot Zaharie Ahmad Shah had gone rogue.

A final report into the tragedy released in 2018 pointed to failings by air traffic control and said the course of the plane was changed manually.

Investigators said in the 495-page report that they still did not know why the plane vanished and refused to rule out that someone other than the pilots had diverted the jet.

Relatives of passengers lost on the flight have continued to demand answers from Malaysian authorities.

Family members of Chinese passengers gathered in Beijing outside government offices and the Malaysian embassy in March on the 11th anniversary of the flight's disappearance.

Attendees of the gathering shouted, "Give us back our loved ones!", with some holding placards asking, "When will the 11 years of waiting and torment end?"

An international team of scientists, led by Olaf Scholten, Professor of Astrophysics at the University of Groningen, has observed radio wave-emissions originating from a commercial airliner, most likely caused by the discharge of static electricity. The serendipitous observation of radio wave emissions from specific locations on the aircraft may be of interest to the aviation industry. In addition, this has already enabled the team to identify a source of error in their imaging techniques. The results were published on 26 November in the journal Nature Communications.

Static electricity builds up through friction, for example, between your clothes and the fabric of your chair, but also in aeroplanes when they pass through frozen clouds. Aeroplanes are therefore fitted with electrostatic discharge wicks, which are designed to shed electrostatic charges in a way that does not cause dangerous sparks or interfere with the aircraft’s communications. Interestingly, the discharges observed by Scholten and his team, while the aeroplane was cruising at an altitude of 8 kilometres, were located around the two engines and at one spot on the tail, rather than at the electrostatic discharge wicks. The events near the tail were measured with an accuracy of about 50 cm.

Of interest to the aviation industry

The observation was made using the Low-Frequency Array (LOFAR) radio telescope, an antenna network located mainly in the Netherlands and spanning seven other European countries. This telescope is primarily used for astronomy, but also for studying the formation of lightning. In previous work, Scholten and his colleagues used LOFAR to make the most detailed lightning images in the world. Thanks to the serendipitous discovery of the aircraft’s emissions, the researchers were able to improve their technique, which will make lightning detections even more accurate in the future.

Flight data revealed that the observed aircraft was a Boeing 777-306 (ER) from the Dutch airline KLM. After searching their archives, Scholten and his colleagues found emissions from a second aircraft, flying at an altitude of 11.6 km. These emissions were also located around the engines and at one point on the tail.  These observations demonstrate that it is possible to use LOFAR to study the accumulation and discharge of electricity by aircraft flying through clouds. Scholten: ‘This would be of interest to the aviation industry, as static charges can create sparks that may damage the plane.’

Research Background

In an era where climate change looms large, the aviation industry—responsible for 3%–4% of global CO2 emissions and growing—faces immense pressure to go green without grounding our connected world. Aviation powers trillions in economic activity and millions of jobs, yet its reliance on fossil fuels spews not just CO2 but also NOx, particulates, and other pollutants that harm air quality and accelerate global warming. Enter hydrogen: a boundless, clean-burning fuel that could slash in-flight emissions to zero. But harnessing it means conquering storage challenges onboard aircraft. This survey dives into cutting-edge hydrogen tank technologies, exploring how to safely store gaseous or liquid hydrogen amid extreme pressures and frigid temperatures, all while integrating seamlessly into plane designs. By reviewing materials, structures, and innovations, it highlights hydrogen's role in aligning aviation with global sustainability goals, making eco-friendly flights not just a dream, but an impending reality.

 

Results and Benefits

This comprehensive review uncovers key advancements in hydrogen storage that promise to transform aviation. For gaseous hydrogen (GH2), high-pressure tanks made from advanced composites withstand internal pressures up to thousands of psi, while liquid hydrogen (LH2) storage tackles cryogenic conditions as low as -253°C with superior insulation to prevent boil-off. The survey spotlights materials like carbon fiber-reinforced polymers, which offer exceptional strength-to-weight ratios—crucial since hydrogen tanks can be four times larger than kerosene ones yet must not add undue weight. Experimental data from projects like the EU's Cryoplane initiative show that LH2 tanks achieve up to 70%–85% efficiency in hydrogen production via steam reforming, with potential jumps to 60%+ for green electrolysis methods using renewables.

 

Socially, these breakthroughs mean cleaner skies: hydrogen eliminates CO2 emissions during flight, potentially reducing aviation's climate footprint by 100% if produced greenly. Economic perks include lower operating costs once hydrogen prices match kerosene's around 2040, as projected in studies, with direct operating costs possibly dropping slightly under optimal conditions. Plus, safer designs incorporating structural health monitoring could cut maintenance hikes (estimated at 22%–32% initially) and enhance reliability, supporting 65.5 million jobs in aviation while fostering new industries in hydrogen production and infrastructure. Real-world tests, like the Soviet TU-155's hydrogen engine flights, prove feasibility, paving the way for reduced noise, better air quality, and a sustainable transport lifeline for global economies.

 

Future Application Prospects

Looking ahead, hydrogen tanks could revolutionize aircraft from short-haul commuters to long-range jets. Imagine retrofitting existing "tube-and-wing" planes with passively insulated cryogenic composite tanks, enabling quick adoption without full redesigns. For broader impact, unconventional aircraft shapes—like blended wings—could optimize LH2 storage, boosting range and efficiency. Further research should focus on cryogenic-resistant composites to minimize hydrogen embrittlement, where materials weaken under H2 exposure, and advanced insulation to curb thermal losses.

 

Practically, airports might integrate on-site green hydrogen production via solar or wind (with grid upgrades multiplying capacity 1.59 times), alongside storage matching three days' kerosene reserves. This could spawn hybrid systems blending hydrogen with biofuels or batteries, slashing NOx hotspots through better combustion mixing. Ongoing projects, such as those from companies like Airbus and Boeing, hint at commercial prototypes by 2030, with refinements in manufacturing processes potentially halving tank weights. Ultimately, these applications could decarbonize aviation entirely, inspiring similar shifts in shipping and automotive sectors for a greener planet.

 

Conclusion

This survey boldly underscores hydrogen tanks as a game-changer for sustainable aviation, blending innovative materials and designs to overcome storage hurdles and unlock zero-emission potential. By addressing embrittlement, insulation, and efficiency, it charts a path to aircraft that rival kerosene in performance while safeguarding our environment. As governments, researchers, and industry collaborate, hydrogen-powered flight isn't just innovative—it's essential for a thriving, eco-balanced future where the skies remain open to all.

A New Gold(en) Mine for Arms Contractors

by  and  | Nov 21, 2025 

Reprinted from TomDispatch:

Donald Trump remains a mystery man of some eerie sort. After all, just ask yourself, why in the world did he only recently announce that this country was going to “immediately” resume nuclear testing, not having tested a nuclear weapon — despite its vast arsenal — since 1992? “Because of other countries testing programs,” he wrote on (of course!) Truth Social, “I have instructed the Department of War to start testing our Nuclear Weapons on an equal basis. That process will begin immediately.” Admittedly, such an idea has been in the air (if that’s even the word for it) for months, but now the president has it on his increasingly strange mind, which is ominous indeed.

No matter, of course, that to use the only nuclear test site available would take at least a couple of years of preparation and cost hundreds of millions of dollars, or that no other country has recently tested a nuclear weapon, or that a significant number of Democrats in Congress are lobbying for him to drop his “dangerously provocative” idea. When it comes to the destruction of this planet — whether atomically or in climate-change fashion — there’s no question that Donald Trump is at the front of the classroom waving his hand like mad.

Of course, as TomDispatch regulars Bill Hartung and Ashley Gate point out today, he has long been wildly in favor of building a “Golden Dome” nuclear defense system that would prove a remarkable (and remarkably costly) boon for the corporations of what still passes as the “defense” industry, even if it would do nothing whatsoever for the rest of us. Let them fill you in on that nightmare project of our moment and the president who seems intent on recreating a nuclear arms race globally on a planet that already has enough problems to deal with. What a nightmare! ~ Tom Engelhardt


Doomed, Not Domed? The Wrath of the Con Man

By Ashley Gate and William D. Hartung

Kathryn Bigelow’s new nuclear thrillerA House of Dynamite, has been criticized by some experts for being unrealistic, most notably because it portrays an unlikely scenario in which an adversary chooses to attack the United States with just a single nuclear-armed missile. Such a move would, of course, leave the vast American nuclear arsenal largely intact and so invite a devastating response that would undoubtedly largely destroy the attacker’s nation. But the film is strikingly on target when it comes to one thing: its portrayal of the way one U.S. missile interceptor after another misses its target, despite the confidence of most American war planners that they would be able to destroy any incoming nuclear warhead and save the day.

At one point in the film, a junior official points out that U.S. interceptors have failed almost half their tests, and the secretary of defense responds by bellowing: “That’s what $50 billion buys us?”

In fact, the situation is far worse than that. We taxpayers, whether we know it or not, are betting on a house of dynamite, gambling on the idea that technology will save us in the event of a nuclear attack. The United States has, in fact, spent more than $350 billion on missile defenses since, more than four decades ago, President Ronald Reagan promised to create a leak-proof defense against incoming intercontinental ballistic missiles (ICBMs). Believe it or not, the Pentagon has yet to even conduct a realistic test of the system, which would involve attempting to intercept hundreds of warheads traveling at 1,500 miles per hour, surrounded by realistic decoys that would make it hard to even know which objects to target.

Laura Grego of the Union of Concerned Scientists has pointed out that the dream of a perfect missile defense — the very thing Donald Trump has promised that his cherished new “Golden Dome” system will be — is a “fantasy” of the first order, and that “missile defenses are not a useful or long-term strategy for defending the United States from nuclear weapons.”

Grego is hardly alone in her assessment. A March 2025 report by the American Physical Society found that “creating a reliable and effective defense against even [a] small number of relatively unsophisticated nuclear-armed ICBMs remains a daunting challenge.” Its report also notes that “few of the main challenges involved in developing and deploying a reliable and effective missile defense have been solved, and… many of the hard problems we identified are likely to remain so during and probably beyond” the 15-year time horizon envisioned in their study.

Despite the evidence that it will do next to nothing to defend us, President Trump remains all in on the Golden Dome project. Perhaps what he really has in mind, however, has little to do with actually defending us. So far, Golden Dome seems like a marketing concept designed to enrich arms contractors and burnish Trump’s image rather than a carefully thought-out defense program.

Contrary to both logic and history, Trump has claimed that his supposedly leak-proof system can be produced in a mere three years for $175 billion. While that’s a serious chunk of change, analysts in the field suggest that the cost is likely to be astronomically higher and that the president’s proposed timeline is, politely put, wildly optimistic. Todd Harrison, a respected Pentagon budget analyst currently based at the conservative American Enterprise Institute, estimates that such a system would cost somewhere between $252 billion and $3.6 trillion over 20 years, depending on its design. Harrison’s high-end estimate is more than 20 times the off-hand price tossed out by President Trump.

As for the president’s proposed timeline of three years, it’s wildly out of line with the Pentagon’s experience with other major systems it’s developed. More than three decades after it was proposed as a possible next-generation fighter jet (under the moniker Joint Strike Fighter, or JSF), for example, the F-35, once touted as a “revolution in military procurement,” is still plagued by hundreds of defects, and the planes spend almost half their time in hangars for repair and maintenance.

Proponents of the Golden Dome project argue that it’s now feasible because of new technologies being developed in Silicon Valley, from artificial intelligence to quantum computing. Those claims are, of course, unproven, and past experience suggests that there is no miracle technological solution to complex security threats. AI-driven weapons may be quicker to locate and destroy targets and capable of coordinating complex responses like swarms of drones. But there is no evidence that AI can help solve the problem of blocking hundreds of fast-flying warheads embedded in a cloud of decoys. Worse yet, a missile defense system needs to work perfectly each and every time if it is to provide leak-proof protection against a nuclear catastrophe, an inconceivable standard in the real world of weaponry and defensive systems.

Of course, the weapons contractors salivating at the prospect of a monstrous payday tied to the development of Golden Dome are well aware that the president’s timeline will be quite literally unmeetable. Lockheed Martin has optimistically suggested that it should be able to perform the first test of a space-based interceptor in 2028, three years from now. And such space-based interceptors have been suggested as a central element of the Golden Dome system. In other words, Trump’s pledge to fund contractors to build a viable Golden Dome system in three years is PR or perhaps PF (presidential fantasy), not realistic planning.

Who Will Benefit from the Golden Dome?

The major contractors for Golden Dome may not be revealed for a few months, but we already know enough to be able to take an educated guess about which companies are likely to play central roles in the program.

The administration has said that Golden Dome will be built on existing hardware and the biggest current producers of missile defense hardware are Lockheed Martin, Boeing, and Raytheon (a major part of RTX Corporation). So, count on at least two of the three of them. Emerging military tech firms like SpaceX and Anduril have also been mentioned as possible system integrators. In other words, one or more of them would help coordinate development of the Golden Dome and provide detection and targeting software for it. The final choice for such an extremely lucrative role is less than certain, but as of now Anduril seems to have an inside track.

Even after the breakup of the Donald Trump/Elon Musk bromance, the tech industry still has a strong influence over the administration, starting with Vice President JD Vance. He was, after all, employed and mentored by Peter Thiel of Palantir, the godfather of the recent surge of military research and financing in Silicon Valley. Thiel was also a major donor to his successful 2022 Senate campaign, and Vance was charged with fundraising in Silicon Valley during the 2024 presidential campaign. Emerging military tech moguls like Thiel and Palmer Luckey, along with their financiers like Marc Andreessen of the venture capital firm Andreessen Horowitz, view Vance as their man in the White House.

Other military tech supporters in the Trump administration include Deputy Secretary of Defense Stephen Feinberg, whose company, Cerberus Capital, has a long history of investing in military contractors and is already pressing to reduce regulations on weapons firms in line with Silicon Valley’s wish list; Michael Obadal, a senior director at the military tech firm Anduril, who is now deputy secretary of the Army; Gregory Barbaccia, the former head of intelligence and investigations at Palantir, who is now the federal government’s chief information officer; Undersecretary of State Jacob Helberg, a former executive at Palantir; and numerous key members of Elon Musk’s Department of Government Efficiency, which took a wrecking ball to civilian bodies like the U.S. Agency for International Development while sparing the Pentagon significant cuts.

Some analysts foresee a funding fight in the offing between those Silicon Valley military tech firms and the Big Five firms (Boeing, General Dynamics, Lockheed Martin, Northrop Grumman, and RTX) that now dominate Pentagon contracting. But the Golden Dome project will have room for major players from both factions and may prove one area where the old guard and the Silicon Valley military tech crew join hands to lobby for maximum funding.

The nation’s premier defense firms and missile manufacturers will likely enjoy direct access to Golden Dome, since the project is expected to be headquartered in Huntsville, Alabama, the “Pentagon of the South.” That self-described “Rocket City” houses the U.S. Missile Defense Agency and a myriad of defense firms (including Lockheed Martin, RTX, General Dynamics, and Boeing). It will also soon host the new Space Force headquarters.

While Huntsville has been a hub for missile defense since President Ronald Reagan’s failed ICBM defense efforts, what makes this placement particularly likely is the significance of Huntsville’s Republican representatives in Congress, particularly Congressman Dale Strong. “North Alabama has played a key role in every former and current U.S. missile defense program and will undoubtedly be pivotal to the success of Golden Dome,” he explained, having received $337,600 in campaign contributions from the defense sector during the 2023-2024 election cycle and cofounded the House Golden Dome Caucus.

His advocacy for the project dovetails well with the power vested in House Armed Services Committee Chairman Mike Rogers (also from Alabama), who received $535,000 from the defense sector during the 2024 campaign. Senator Tommy Tuberville, a senior member of the Senate Armed Services Committee, and Senator Katie Boyd Britt, a member of the Senate Golden Dome Caucus, round out Alabama’s Republican Senate delegation.

Many of the leading boosters of the Golden Dome represent states like Alabama or districts that stand to benefit from the program. The bicameral congressional Golden Dome caucuses include numerous members from states already enmeshed in missile production, including North Dakota and Montana, which house ICBMs built and maintained by Northrop Grumman and Lockheed Martin, among other companies.

Those same weapons companies have long been donating generously to political campaigns. And only recently, to curry favor and prove themselves worthy of Golden Dome’s lucrative contracts, Palantir and Booz Allen Hamilton joined Lockheed Martin in donating millions of dollars to President Trump’s new ballroom that is to replace the White House’s devastated East Wing. And expect further public displays of financial affection from arms companies awaiting the administration’s final verdict on Golden Dome contracts, which will likely be announced in early 2026.

The Gold of the Golden Dome

Golden Dome is already slated to receive nearly $40 billion in the next year when funds from President Trump’s “big beautiful bill” and the administration’s budget request for Fiscal Year 2026 are taken into account. The 2026 request for Golden Dome is more than twice the budget of the Centers for Disease Control and three times the budget of the Environmental Protection Agency, essential pillars of any effort to prevent new pandemics or address the challenges of the climate crisis. In addition, Golden Dome will undoubtedly siphon into the military sector significant numbers of scientists and engineers who might otherwise be trying to solve environmental and public health problems, undermining this country’s ability to deal with the greatest threats to our lives and livelihoods to fund a defense system that will never actually be able to defend us.

Worse yet, Golden Dome is likely to be more than just a waste of money. It could also accelerate the nuclear arms race between the U.S., Russia, and China. If, as is often the case, U.S. adversaries prepare for worst-case scenarios, they are likely to make their plans based on the idea that Golden Dome just might work, which means they’ll increase their offensive forces to ensure that, in a nuclear confrontation, they are able to overwhelm any new missile defense network. It was precisely this sort of offensive/defensive arms race that the Anti-Ballistic Missile Treaty of the era of President Richard Nixon was designed to prevent. That agreement was, however, abandoned by President George W. Bush.

A no less dangerous aspect of any future involving the Golden Dome would be the creation of a new set of space-based interceptors as an integral part of the system. An interceptor in space may not actually be able to block a barrage of nuclear warheads, but it would definitely be capable of taking out civilian and military satellites, which travel in predictable orbits. If the unspoken agreement not to attack such satellites were ever to be lifted, basic functions of the global economy (not to speak of the U.S. military) would be at risk. Not only could attacks on satellites bring the global economy to a grinding halt, but they could also spark a spiral of escalation that might, in the end, lead to the use of nuclear weapons.

Should the Golden Dome system indeed be launched (at a staggering cost to the American taxpayer), its “gold” would further enrich already well-heeled weapons contractors, give us a false sense of security, and let Donald Trump pose as this country’s greatest defender ever. Sadly, fantasies die hard, so job number one in rolling back the Golden Dome boondoggle is simply making it clear that no missile defense system will protect us in the event of a nuclear attacka point made well by A House of Dynamite. The question is: Can our policymakers be as realistic in their assessment of missile defense as the makers of a major Hollywood movie? Or is that simply too much to ask?
