A long-standing ban on commercial supersonic flights over the United States would be overturned in a new rule proposed by the US Federal Aviation Administration. That could pave the way for the possible return of commercial supersonic airliners—as long as such aircraft can reduce the ground-level impacts of their sonic booms.

The FAA originally banned overland supersonic flights by civil aircraft in 1973, following US military tests involving supersonic flights over US cities such as Oklahoma City, Chicago, and St. Louis in the 1960s. But the Trump administration has championed the repeal of the ban to pave the way for supersonic airliners that could operate without disruptive sonic booms. So the FAA’s new rulemaking action on June 30, 2026, follows the direction of an executive order issued by President Trump on June 6, 2025.

The newly proposed rule would replace the 53-year prohibition with an interim “noise-based” certification standard requiring any sonic boom overpressure at the surface to be kept below 0.11 pounds per square foot. That proposed standard is based on the Colorado-based startup Boom Supersonic having demonstrated quiet Mach cutoff flights with its XB-1 aircraft—harnessing specific atmospheric conditions while flying just beyond supersonic speeds at higher altitudes so that the aircraft’s shockwaves are refracted upward into the atmosphere rather than traveling to the ground.

OpenAI CEO Sam Altman is reportedly in active talks with the Trump administration about the US potentially acquiring a 5 percent stake in the leading AI firm.

Insider sources told the Financial Times that these talks are in “early stages,” but Altman “has argued that giving the public a financial stake in the company is the best way to share the upside of AI.”

Donald Trump favors the idea, and his administration has reportedly been talking to several AI firms about the possibility. According to FT’s sources, other companies approached to share similar stakes include Google and Meta.

Ahead of a July 2 deadline to submit public comments, advocates are warning the Federal Trade Commission that it must keep close watch over Elon Musk’s X and firmly reject a recent bid to end the agency’s ongoing audits of the platform’s data handling.

Last month, the FTC posted a notice explaining that X had argued that an FTC order was no longer necessary due to changes Musk had made to the platform.

The initial order came as a penalty after the FTC found that a coding error had caused then-Twitter to improperly share users’ contact information for ad targeting that had initially been submitted for two-factor authentication. Under the order, X is subjected to costly independent audits, and the FTC has authority to demand documents to ensure compliance with data privacy laws without taking additional legal action.

The US has lifted export curbs on Anthropic’s newest Claude models, Fable 5 and Mythos 5, about three weeks after the Trump administration flagged the models as national security risks.

As of today, Anthropic confirmed in a blog post, Fable 5 will be available globally, and US organizations have had access restored to Mythos 5 since June 26. Anthropic said it is now working with the government to expand Mythos access to a “broader set of domestic and international partners in the Glasswing program.” That program allows cybersecurity researchers at trusted companies to access Mythos for defensive purposes.

In a letter to Anthropic viewed by Reuters and The New York Times, Commerce Secretary Howard Lutnick said Anthropic would “no longer need a license for exports or in-country transfers of its Claude Mythos and Claude Fable AI models.” The letter acknowledged that Anthropic had “taken steps in close coordination with the US government to address the risks” posed by the models.

The British government could intervene in the $111 billion takeover of Warner Bros. Discovery by Paramount Skydance, citing concerns around the need for a plurality of views in news as well as media ownership in the UK.

UK culture secretary Lisa Nandy said on Tuesday that she was “minded to intervene” in the deal, which would create one of the world’s largest media and entertainment groups.

The takeover would lead to WBD media franchises such as CNN, HBO, and Warner Bros. movies being added to Paramount’s stable of assets, which include CBS in the US and Channel 5 in the UK.
