This Is Why

As America marks the 25th anniversary of the September 11th terror attacks, a row has erupted between the man who led New York through its darkest moments and the city’s current mayor.

Rudy Giuliani became the face of New York’s resilience following the fall of the Twin Towers, but he warned Zohran Mamdani to stay away from official memorial events.

Mamdani, the city’s first ever Muslim mayor, ignored his predecessor advice – despite being compared by Giuliani to the al Qaeda terrorists who carried out the 9/11 atrocities.

Is Giuliani’s ire racially motivated? What brought about the former Trump ally’s own fall from grace? And what have native New Yorkers made of Mamdani’s time in charge?

Don’t worry, AI’s not preparing to wipe out humanity with a Terminator-style nuclear Armageddon – that's just not its style.

But could it develop a virus that does the job instead? Well, that seems more of a possibility....

And speaking of odds, both former and current employees of tech giant Anthropic put the chances of AI ending all human life at roughly 10 percent. They only differ on the timescale.

With seemingly no end to the breathtaking pace of development, is it too late for governments to intervene? And as experts increasingly acknowledge AI could cause existential change, how exactly could that happen?

Less up, up and away... more stuck on the tarmac. Hundreds of flights have been cancelled and thousands of passengers stranded after yet another critical collapse of the country’s air traffic control system.

While a cyber-attack has been ruled out, it’s still the third time in four years severe disruption has affected airlines and travellers because of problems at NATS – a public-private partnership and the UK’s leading provider of air traffic control services.

Why do these issues keep happening? Should the government intervene? And is it only a matter of time before passenger safety is compromised?

Niall Paterson speaks to aviation expert and former air traffic controller, Doug Maclean.

Imagine your child has been the victim of a terror attack. Then imagine the most intimate details of their injuries being viewed and shared without your permission or knowledge.

A Sky News and Health Service Journal investigation has uncovered the extent to which NHS staff are accessing patients’ medical records.

High profile cases include the victims of the Nottingham and Southport attacks. But information was also accessed to carry out coercive control and domestic abuse.

Niall Paterson speaks to Sky’s health correspondent, Ashish Joshi, and Zoe Tidman – senior correspondent for the Health Service Journal.

NHS England has issued a response to the investigation, saying: “All NHS trusts are required to maintain audit logs of access to patient information as well as having controls in place to prevent and identify unauthorised access – and must take action in cases where staff have abused the trust of patients by accessing personal records without good reason.”

We have become used to seeing protests against small boat arrivals in the UK, but the speed and size of those in Dover and Portsmouth over the weekend felt like something new.

The demonstrations were led by a group founded by Daniel Thomas - a friend of far-right activist Tommy Robinson - who described the protests as "only the beginning".

Local authorities were seemingly caught out by events. So, will we now see more similar demonstrations? And what can the police do?
