Jet that could fly from London to NYC in 3.5 hours steps closer to reality

Concorde-style flights capable of blasting passengers from London to New York City in 3.5 hours have edged closer to reality after a major ban was lifted.
'Son of Concorde' maker Boom Technology has welcomed President Trump's executive order that effectively lifts the 52-year ban on civil supersonic flight over land in the US.
Tight restrictions on supersonic flights have been in place due to the loud sonic boom created by the shock waves from a flying object travelling faster than the speed of sound.
'America once led the world in supersonic aviation, but decades of stifling regulations grounded progress,' the White House said.
'This Order removes regulatory barriers so that US companies can dominate supersonic flight once again.'
To hit supersonic speeds, an aeroplane needs to travel at 768 miles (1235km/h) per hour.
But Boom Technology has been working on a jet that has no audible sonic boom.
The firm managed to make its XB-1 test jet fly faster than the speed of sound for the first time in January this year.
Writing on X, the company welcomed the latest move, saying: 'Thank you, President Trump, for unlocking the future of faster and quieter travel.'
'This presidential action comes after a bipartisan group of key Congressional leaders introduced the Supersonic Aviation Modernization Act on May 14, 2025.
'The legislation calls on the FAA to revise the regulation prohibiting supersonic flight over land.'
After finishing tests with XB-1 in January, Boom is now focused on building a plane suitable for passengers called Overture.
Some 130 aircraft pre-orders have already been made by the likes of American Airlines, United Airlines, and Japan Airlines.
The executive order does come with a set of rules that the Administrator of the Federal Aviation Administration (FAA) has been directed to impose.
An interim 'noise-based certification standard' must be established that considers 'community acceptability, economic reasonableness, and technological feasibility'.
Trump was presented with a miniature model of Overture earlier this year from Boom Technology's CEO.
He suggested that Boom should manufacture Air Force One - the President's personal plane - and made a dig at China President Xi Jinping.
'Air Fore Once should be supersonic. Xi [President of China] can keep his 747-8,' he wrote.

Donald Trump rejects spy chief's take on Iran nuclear program

US Director of National Intelligence Tulsi Gabbard is wrong in suggesting there is no evidence Iran is building a nuclear weapon, President Donald Trump says. Trump contested intelligence assessments relayed earlier in 2025 by his spy chief that Tehran was not building a nuclear weapon when he spoke with reporters at an airport in Morristown, New Jersey. 'She's wrong,' Trump said on Friday. In March, Gabbard testified to Congress that the US intelligence community continued to believe that Tehran was not building a nuclear weapon. 'The (intelligence community) continues to assess that Iran is not building a nuclear weapon,' she said. On Friday, Gabbard said in a post on X that: 'America has intelligence that Iran is at the point that it can produce a nuclear weapon within weeks to months, if they decide to finalise the assembly. President Trump has been clear that can't happen, and I agree.' She said the media has taken her March testimony 'out of context' and was trying to 'manufacture division'. The White House has said Trump would weigh involvement in the Iran-Israel conflict over the next two weeks. On Tuesday, Trump made similar comments to reporters about Gabbard's assessment. Israeli Prime Minister Benjamin Netanyahu has justified a week of air strikes on Iranian nuclear and military targets by saying Tehran was on the verge of having a warhead. Iran denies developing nuclear weapons, saying its uranium enrichment program is only for peaceful purposes. In March, Gabbard also described Iran's enriched uranium stockpile as unprecedented for a state without such weapons and said the government was watching the situation closely. She also said Iran had started discussing nuclear weapons in public, 'emboldening nuclear weapons advocates within Iran's decision-making apparatus'. A source with access to US intelligence reports told Reuters the March assessment presented by Gabbard has not changed. Trump has frequently disavowed the findings of US intelligence agencies, which he and his supporters have charged — without providing proof — are part of a 'deep state' cabal of US officials opposed to his presidency.

The ‘sandwich generation' and the age of caring

Pressing question It was once not much more than a figure of speech 'the president has his finger on the button'. Now I want to know exactly what pressing that button will mean. Elizabeth Howcroft, Hawthorn Human rights for all In response to your correspondent (Letters, 20/6), first, describing Israel's actions since 2006 as ″⁣restraint″⁣ ignores reality. Its withdrawal was followed by a blockade of Gaza, collectively punishing 2.3million people. This siege, intensified since 2023, restricts food, water, medicine, and movement, constituting unlawful collective punishment under international law. Decades of military operations have caused morally unacceptable civilian suffering. Second, labelling Israel the region's ″⁣only democratic state″⁣ whitewashes its systemic discrimination against Palestinians. Within Israel, Palestinian citizens face overwhelming inequality. In the occupied territories, millions live under military rule without basic rights. Leading human rights organisations, including Israeli ones, conclude this system meets the definition of apartheid. Finally, while criticising neighbouring states, your correspondent overlooks that Israel's prolonged occupation, settlement expansion (illegal under international law), and actions in Gaza represent a severe violation of Palestinian rights. Calling for accountability isn't scapegoating; it's demanding adherence to universal human rights. Paul Evans, Carrum Downs Talking obstacles Foreign Minister Penny Wong says Iran should return to the table to negotiate on nuclear disarmament. It did that in 2015 when, with the Obama government, it agreed to restrict uranium enrichment. In 2017, new president Donald Trump dumped the deal. Why should the Iranians believe anything would be different today? Now both Trump and Benjamin Netanyahu want to inflict more attacks on Iran. Wong couldn't be ignorant of this history, so the question is why is she calling for negotiations when she should be aware that neither the Israelis nor Trump would actually want to take part in them in a meaningful way? Noel Turnbull, Port Melbourne Tax reset, please Congratulations to Treasurer Jim Chalmers for acting on tax reform and national productivity (″⁣Gentle Jim levels path to reform″⁣, 21/6). With ″⁣gotcha″⁣ questions and negative reporting of any tax change, no wonder he avoided this at the election. Neither major party made it an issue. Even with balanced discussion and logical rationalisation of taxes, there will be lobbying by vested interests. The Ken Henry Tax Review of 2009 offered 138 recommendations. These included one that would raise much-needed revenue – the Resource Super Profits Tax. This was sunk by the mining industry. In fact, very few of those tax review recommendations were implemented. Australia clearly needs a tax reset, integrated with productivity and overall fairness considerations. Perhaps Ken Henry can assist. John Hughes, Mentone Not really a majority It is true, as your correspondent says (Letters, 20/6), that Donald Trump was comfortably elected, but we should be aware of what this means in America. Only a minority of eligible US voters (less than a third) actually cast a vote for him. Well over 30 per cent preferred Kamala Harris while the largest group, about 35 per cent, did not vote. To say that most Americans really wanted another Trump administration is stretching reality. Peter McCarthy, Mentone On limited time Benjamin Netanyahu claims regime change is his aim in Iran and Gaza. It seems like regime maintenance – his own, due to the biggest security failure in Israel, on his watch. Whenever the bombings cease, his political career is done. Patrick Alilovic, Pascoe Vale South Blackadder returns US President and Commander-in-Chief Donald Trump's 'very clever ruse to lull the Iranians into a sense of complacency' (' Trump buys himself time, and opens up new options as Israel goes all out ', 21/6), is the sort of 'cunning plan' you might expect from Private S. Baldrick in Blackadder. Lawrie Bradly, Surrey Hills Bombs over boots Remembering the Iraq invasion, the US will no doubt prefer bunker-busting bombs to boots on the ground. Greg Curtin, Nunawading Heart of the matter Life mimics art, again: Monash Health is having its Yes, Minister moment (″⁣Madness as $600m heart hospital cuts theatre, beds', 21/6). No point in building a state-of-the-art facility if it cannot meet the demand for care. Another example of what can happen when public health services are run by bureaucrats and bean-counters not medical professionals. Jenifer Nicholls, Windsor A selfish kiss Your correspondent (Letters, 20/6) implies that King Priam's display of humility was a peacemaking exercise. It was nothing of the sort. His kiss of Achilles' hand was for the entirely selfish motive of retrieving Patroclus' body. The handover of Helen, which might have ended the war, was a step the Trojans would not take.
