From Queen of the Skies to scrap metal: The life and death of giant planes
At 19, the world's oldest commercial A380 is hardly ancient but – in aircraft years – it's reached an age at which most large jets (the affectionate nickname for all wide, long bodied aircraft) retire to the great boneyards of the desert. Not this one though: after a five-year hiatus, it's back ploughing the skies for Emirates, according to simpleflying.com.
The European Union Aviation Safety Agency (EASA) says that most planes have a life cycle of about 25-30 years, but that includes a long period of research and development before their first commercial flights take off. If you find yourself on a comparatively ancient aircraft, don't worry: planes are subjected to frequent tests to ensure safety and usually retire because they become less commercially competitive rather than dangerous.
The birth of a giant aircraft
A wide-body aeroplane's journey involves a long period of incubation and subsequent nurturing before it can go out into the world. 'The journey from the design board to commercial service for a commercial aircraft is one of the most complex undertakings in modern industrial engineering,' says Linus Benjamin Bauer, founder and managing direction of the aviation consultancy BAA & Partners. 'Typically, the aircraft development programme takes up to 15 years to bring a new aircraft such as the A380 to market.'
The original jumbo, Boeing's 747, was conceived in 1966 and began to fly commercially four years later thanks to tight deadlines imposed by its first purchaser, Pan Am. But, before paying passengers can get onboard, planes face 'initial conceptual studies, customer consultations, digital modelling, prototype development and regulatory certification,' according to Bauer.
'Certification itself is particularly rigorous,' he says. 'Manufacturers must demonstrate compliance with thousands of airworthiness requirements. Each new aircraft must pass a full-scale evacuation test – where all passengers must exit within 90 seconds using only half the available exits. Structural integrity is validated through static testing, where airframes are pushed 50 per cent beyond their design limits, and fatigue testing, which simulates decades of flight cycles.'
These tests can make or break a plane's popularity: when they uncovered issues with weight in some of Boeing's earliest 787 aircraft (nicknamed the 'Terrible Teens'), the planes were rejected by airlines including All Nippon Airways and Royal Air Maroc, according to the website planespotters.net (though they now take to the skies with Ethiopian and Air Austral).

PM urges 'free and fair trade' to US business figures
The prime minister will emphasise the importance of free and fair trade to US business leaders ahead of major talks with world powers. Anthony Albanese landed in Seattle, in the US state of Washington, on Saturday as part of a whirlwind tour that could end in a meeting with US President Donald Trump about his controversial tariffs. Washington state is home to several tech and engineering giants such as Boeing, Microsoft and Amazon, and Mr Albanese will attend the Technology and Innovation Business Reception on Saturday local time to address companies like BHP Ventures, Airwallex and Anthropic. "Free and fair trade has transformed the economies of our region," the prime minister will say in his remarks. "We should not lose sight of the profound opportunities that can be realised by closer and deeper co-operation - the businesses in this room are proof of that. "In a time of global uncertainty, all of you represent cause for optimism." The visit comes after he held security and climate talks in Fiji however, these pit stops play second fiddle to his trip's upcoming centrepiece. Seven of the world's largest advanced economies will gather in Canada from Sunday for the multi-day G7 summit. The event is often used to discuss solutions to major global issues like trade, security, economics and climate change, and in a year largely defined by trade tariffs, the topic is expected to take the spotlight. Australia is not part of the G7 but Mr Albanese has been invited, fuelling speculation he will meet President Trump on the sidelines of the event. The prime minister appears to be preparing for the possibility - his remarks reheat Labor's lines on US tariffs, emphasising Australia will engage "respectfully and constructively" in its national interest. Australia currently faces 10 per cent tariffs on goods exported to the US and - like all US trading partners except the UK - has been hit with 50 per cent tariffs on aluminium and steel sent to America. The Australian government is considering using critical minerals and US beef imports as bargaining chips in tariff talks. However, Mr Albanese has not yet confirmed whether he will sit down with Mr Trump. The prime minister has already had three discussions with the US president as his government, including Australia's ambassador to the US Kevin Rudd, have tried to negotiate a tariff exemption. Mr Albanese will also visit the Amazon corporate headquarters in Seattle to highlight the company's multi-billion-dollar investment in Australian data centres.

India to inspect all Boeing 787s after deadly crash
India's aviation regulator has ordered all Boeing 787s being operated by local carriers to be inspected after an Air India crash killed 270 people this week, the aviation minister said, adding the authorities were investigating all possible causes. The aviation regulator had on Friday ordered Air India to conduct additional maintenance checks on its Boeing 787-8/9 aircraft equipped with GEnx engines, including assessments of certain take-off parameters, electronic engine control tests and engine fuel-related checks. "We have also given the order to do the extended surveillance of the 787 planes. There are 34 in our Indian fleet," aviation minister Ram Mohan Naidu told reporters in New Delhi. "Eight have already been inspected and with immediate urgency, all of them are going to be done." He did not say whether government officials will be involved in the inspections. The Boeing 787-8 Dreamliner with 242 people on board bound for Britain's Gatwick Airport began losing height seconds after take-off on Thursday and erupted in a fireball as it hit buildings below, in what has been the world's worst aviation disaster in a decade. Air India operates 33 Boeing 787s, while rival airline IndiGo has one, according to data from Flightradar24. IndiGo did not respond to a request for comment. In a statement, Air India said it is currently completing the one-time safety checks directed by the Indian regulator, adding that "some of these checks could lead to higher turnaround time and potential delays on certain long-haul routes." The planes, however, have not been grounded, but a source on Friday told Reuters the Indian government was considering that as an option. Naidu also said the government will look at all possible theories of what led to the crash. Air India and the Indian government were looking at several aspects of the crash including issues linked to its engine thrust, flaps, and why the landing gear remained open as the plane took off and then came down, Reuters has reported. At least 270 bodies have been recovered from the site of the crash, Dhaval Gameti, president of the Junior Doctors Association at BJ Medical College, told reporters. Only one of the 242 passengers and crew on board survived while others were killed as the plane struck the medical college's hostel as it came down. Naidu said a government panel was investigating the crash and will issue a report within three months. "We are going to improve every necessary thing that is going to come our way, to improve the safety," he said at the briefing, declining questions from journalists. Later in the afternoon, authorities removed the tail of the aircraft that was stuck on top of a building, while hospital and rescue officials said a body of a cabin crew member was recovered from the wreckage. Air India said it will provide an interim payment of 2.5 million rupees ($A45,000) each to the families of the deceased and to the survivor, to help address immediate financial needs, in addition to 10 million rupees ($A180,000) in support announced previously by the Tata Group. "The process of reuniting next of kin with their loved ones and personal effects has begun," Air India CEO Campbell Wilson said in a statement, as authorities started handing over bodies of passengers and crew members to their families, nearly 48 hours after the crash. Dozens of anxious family members have been waiting outside an Ahmedabad hospital to collect the bodies, as doctors were working overtime to gather dental samples from the deceased to run identification checks and DNA profiling.
