US civilian jet breaks sound barrier in California test flight
An American civil aircraft broke the sound barrier for the first time in California's Mojave Desert, a US aviation company announced on Wednesday.
The XB-1, a demonstrator jet that resembles a military plane, successfully achieved the benchmark during a flight on Tuesday, according to Boom Supersonic, which aims to bring back a type of highspeed travel that went away after the Concorde was wound down in 2003.
The flight took place in the same airspace where US test pilot Chuck Yeager broke the sound barrier for the first time in 1947.
'XB-1's supersonic flight demonstrates that the technology for passenger supersonic flight has arrived,' said Boom founder and CEO Blake Scholl.
'Next, we are scaling up the technology on XB-1 for the Overture supersonic airliner. Our ultimate goal is to bring the benefits of supersonic flight to everyone.'
Boom is developing a commercial jet called Overture, which is designed to carry as many as 80 passengers at Mach 1.7, about twice the speed of today's commercial airlines.
The jet's maximum range is 4,888 miles (7,867 kilometers) and it is designed to fly between Miami and London in less than five hours, compared with the eight and a half hours on current planes.
Boom has 130 orders and pre-orders from American Airlines, United Airlines, and Japan Airlines.
The jets will be 'net-zero' in carbon use because they will use renewable fuel.
Boom last year opened a factory in Greensboro, North Carolina, where it can produce 33 planes per year, with the potential to double that volume once a second production line is added.
Commercial supersonic jet travel was introduced in the 1970s with the Concorde, but the jets were retired in 2003, due to due environmental concerns and after a 2000 Air France accident that killed 113 people.

US aerospace industry anxious as tariffs loom
AFP | New York US airlines and aerospace manufacturers insist they have no use for tariff protections, warning that the proposed Trump administration levies could eat into the healthy trade surplus the sector has enjoyed for more than 70 years. At the request of President Donald Trump, Commerce Secretary Howard Lutnick's department launched an investigation on May 1 to determine whether to impose tariffs of between 10 and 20% on civil aircraft and parts, including engines. The US industry those tariffs were crafted to protect swiftly let the administration know it was not interested. 'Imposing broad tariff or non-tariff trade barriers on the imports of civil aviation technology would risk reversing decades of industrial progress and harm the domestic supply chain,' the Aerospace Industries Association (AIA) said in a letter addressed to Lutnick and obtained by AFP. The interested parties were given until June 3 to communicate their positions. The very next day, Lutnick announced that Washington aimed to 'set the standard for aircraft part tariffs' by the end of this month. 'The key is to protect that industry,' he said, adding: 'We will use these tariffs for the betterment of American industry.' But AIA and the Airlines for America (A4A) trade association voiced fear that far from helping, the tariffs would end up harming US manufacturers. No fix needed 'Unlike other industries, the civil aviation manufacturing industry prioritizes domestic production of high-value components and final assembly,' AIA pointed out. According to the organization, US aerospace and defense exports reached $135.9 billion in 2023, including $113.9 billion for civil aviation alone. This allowed the sector to generate a trade surplus of $74.5 billion and to invest $34.5 billion in research and development, it said. The sector employs more than 2.2 million people in the United States across more than 100,000 companies, which in 2023 produced goods worth nearly $545 billion. In its response to Lutnick, the A4A highlighted how beneficial the international Agreement on Trade in Commercial Aviation (ATCA) had been by helping to eliminate tariffs and trade barriers over nearly half a century. 'The US civil aviation industry is the success story that President Trump is looking for as it leads civil aerospace globally,' it insisted. A full 84% of production was already American, it said, stressing that Washington 'does not need to fix the 16 percent' remaining. 'The current trade framework has enhanced our economic and national security and is a critical component to maintaining our national security moving forward,' it said. For manufacturers, the potential tariffs would act like sand jamming a well-oiled machine that has been running smoothly for decades, experts warned. They would also throw off balance an ultra-sensitive supply chain still recovering from the Covid-19 pandemic. 'Competitive disadvantage' 'To avoid the situation getting worse, we advocate to keep aerospace outside of trade wars,' Willie Walsh, head of the International Air Transport Association (IATA), told the organization's general assembly last week. AIA meanwhile stressed that 'aircraft and parts are already in high demand and have a limited supply.' 'Integrating new suppliers and expanding capacity is complex, timely, and costly,' it warned, pointing out that finding suppliers capable of meeting rigorous safety certifications could 'take up to 10 years.' Delta Air Lines also argued for sticking with the status quo, cautioning that the proposed tariffs 'would hinder Delta's ability to maintain its current trajectory.' 'If component parts incur tariffs upon entering the United States, Delta will be at a competitive disadvantage to foreign competitors,' it said. 'The action would also impose an unexpected tax on Delta's purchases of aircraft contracted years in advance.' Delta chief Ed Bastian insisted in late April that the airline 'will not be paying tariffs on any aircraft deliveries we take,' adding that it was 'working very closely with (European group) Airbus' to minimize the impact. Delta pointed out in its letter to Lutnick that it currently had 100 aircraft on order from Boeing, and that it was demanding that its Airbus A220s be produced primarily in Mobile, Alabama. But if the tariffs are imposed, it warned, 'Delta would likely be forced to cancel existing contracts and reconsider contracts under negotiation.'

China vice premier to meet US delegation for trade talks: Beijing
Chinese Vice Premier He Lifeng will meet a US delegation for talks next week in Britain, Beijing announced Saturday amid a fragile truce in the trade dispute between the two powers. He will visit the United Kingdom from June 8 to 13 at the invitation of the British government, China's foreign ministry said in a statement. It said He and American representatives will co-chair the first meeting of the China-US economic and trade consultation mechanism. US President Donald Trump had already announced on Friday that a new round of trade talks with China would kick off in London beginning Monday, after he spoke by phone with Chinese counterpart Xi Jinping in a bid to end a bitter battle over tariffs. Trump posted on his Truth Social platform that Treasury Secretary Scott Bessent, Commerce Secretary Howard Lutnick and US Trade Representative Jamieson Greer would meet the Chinese team. A first meeting, held in mid-May in Geneva, brought a pause to the US-China trade dispute.

Iran Furious At 'Racist' US Travel Ban Targeting Muslim Nations
At a moment both sides are still engaged in highly sensitive nuclear negotiations, Iran has strongly condemned US President Donald Trump's new travel ban, blasting it as 'racist' and indicative of Washington's deep hostility toward Iranians and Muslims. The executive order restricts travel from 19 countries, primarily in Africa and the Middle East, in a new 'Muslim travel ban' of sorts – given it mirrors similar policies from Trump's first term in office, and will take effect Monday. There are outright bans imposed on a dozen of the nations. Iranian official Alireza Hashemi-Raja criticized the move as reflecting a 'supremacist and racist mentality' among American policymakers. According to more via Al Jazeera: Hashemi-Raja argued that the policy breaches international legal norms and denies millions the basic right to travel, based solely on nationality or faith. He said the ban would 'entail international responsibility for the US government', without elaborating. The ban heavily features Mideast and North African countries like Iran, Afghanistan, Libya, Yemen, Somalia, Sudan, and others – but is not limited to countries with Muslim majority populations. Among the countries listed are also Myanmar, Chad, Republic of Congo, Equatorial Guinea, Eritrea, Haiti. There are 'partial bans' and some new visa restrictions for Burundi, Cuba, Laos, Sierra Leone, Togo, Turkmenistan and Venezuela. President Trump had explained this week in a statement posted to the White House: 'The United States must ensure that admitted aliens and aliens otherwise already present in the United States do not bear hostile attitudes toward its citizens, culture, government, institutions, or founding principles, and do not advocate for, aid, or support designated foreign terrorists or other threats to our national security.' And further: I directed the Secretary of State, in coordination with the Attorney General, the Secretary of Homeland Security, and the Director of National Intelligence, to identify countries throughout the world for which vetting and screening information is so deficient as to warrant a full or partial suspension on the admission of nationals from those countries pursuant to section 212(f) of the Immigration and Nationality Act (INA), 8 U.S.C. 1182(f). After completing that process, the Secretary of State determined that a number of countries remain deficient with regards to screening and vetting. Many of these countries have also taken advantage of the United States in their exploitation of our visa system and their historic failure to accept back their removable nationals. Source: NBC News Interestingly, Syria was on the controversial ban during Trump's first term, but is notably absent this time around – despite the fact that the decade-plus long proxy war saw foreign jihadists flow there from around the world. There are even foreign jihadists who hold government positions in the Jolani (Sharaa) regime, in the wake of Assad's December ouster.
