Chinese paraglider's thundercloud survival claim likely featured AI-faked video
BEIJING : A Chinese paraglider's account of having been unwittingly swept into a thundercloud and dragged 8km into the sky has come under question after his video of the incident, carried by Chinese state media, turned out to have been likely faked in part.
The video, originally posted after the paraglider's May 24 flight by his support team on Douyin, China's TikTok, employed artificial intelligence to fake some of the footage, according to a review by a digital security firm consulted by Reuters.
The video's opening showed Peng Yujiang, 55, among the clouds, his face encrusted with ice.
The video, which caused a sensation in paragliding circles, was aired in China and distributed internationally by state-run broadcaster CCTV.
Other news providers also distributed the video, which was picked up globally.
California-based digital security firm GetReal said it was 'fairly confident' the first five seconds of Peng Yujiang's video contained AI-generated images.
There are also inconsistencies noted by GetReal and paragliders who pored over the video: Peng's legs are initially dangling without the insulating cocoon shown later.
His helmet is first white, then black.
Still, five expert paragliders interviewed by Reuters said it was possible Peng had flown to 8,589m as he claimed and survived.
But four of them also challenged his claim that the flight had been an unavoidable accident, which Reuters is reporting for the first time.
The current record for a planned flight is held by French pilot Antoine Girard who flew 8,407m over a stretch of the Himalayas in 2021.
Peng recorded and then deleted his flight log on XContest, a website popular among paragliders, according to Jakub Havel, a Czech paraglider who helps run the forum.
Havel said other flights by Peng remained on the site.
'Nobody intentionally lets themselves be sucked into a thunderstorm cloud in an attempt to break a record – it's something that any sane paragliding pilot tries to avoid at all costs,' said Havel, who said Peng's flight should not be considered a record.
Peng could not be reached for comment.
CCTV, which distributed the video on a platform owned by Reuters, could not be reached for comment.
Like other Chinese media, CCTV faces a pending regulation from Beijing that requires all AI-generated content to be labelled as such from September.
Contacted on the weekend, China's state council, which oversees and coordinates government policy, had no immediate comment.
In a statement, Reuters said it had removed the CCTV package on Peng's flight from Reuters Connect, an online marketplace that carries material from more than 100 news organisations.
'This content is clearly labelled as third-party content and is not verified or endorsed by Reuters,' the statement said.
'When we became aware of a piece of content that likely contained AI-generated elements on the Reuters Connect platform, we investigated and took it down because the material does not comply with our partner content policy.'
Storm clouds
In a report published on Wednesday, the Gansu Aeronautical Sports Association said Peng had broken an altitude record after being swept off the ground by a strong wind while testing second-hand gear he had just bought.
'According to Peng, he didn't plan on taking off,' the report said.
The association, a private group that oversees air sports in the province, did not respond to a request for comment.
It deleted its report on Peng's flight from its WeChat account and by Thursday the association's website was blocked.
The association suspended Peng from flying for six months.
A member of his flight team was suspended for six months for releasing the video without authorisation.
Expert pilots interviewed by Reuters said there were reasons to doubt Peng's flight was a fluke accident, saying he was either trying to make an unauthorised high ascent or should have seen the risk.
Storm clouds like the one Peng flew in 'don't just appear above your head and hoover you into space. They build over a period of time,' said Daniel Wainwright, a flight instructor in Australia.
'He shouldn't have been flying.'
The specialised heavy mittens shown in the video seem to undercut Peng's claim he had not intended to take off, said Brad Harris, president of the Tasmanian Hang Gliding and Paragliding Association.
He said he believed Peng may have made up the accidental take-off to avoid sanction for entering restricted air space.
'These are not things you would normally wear or have ready if you were just ground-handling to test a wing,' Harris said.
Godfrey Wenness, a former paragliding distance world record holder, said a veteran paraglider could have managed to reverse the extreme but manageable ascent shown in Peng's flight data.
'He was either inexperienced or he was trying to (keep climbing),' Wenness said.
Wenness said, however, he believed Peng hit the altitude he claimed based on flight data posted on XContest and then deleted.
That data has to be transferred from a GPS in a 'tamper-proof' format, he said.
'We conclude and are confident that the actual flight did occur,' he said.

Indonesia offers to cut duties on US goods to ‘near zero' in tariff talks
Indonesian state carrier Garuda will buy more Boeing planes as part of a US$34 billion pact. (AFP pic) JAKARTA : Indonesia has offered to cut duties on key imports from the US to 'near zero' and to buy US$500 million worth of US wheat as part of its tariff talks with Washington, its lead negotiator and a wheat industry association said today. Chief economics minister Airlangga Hartarto, who is Indonesia's lead negotiator, also confirmed that state carrier Garuda Indonesia would buy more Boeing planes as part of a US$34 billion pact with US partners due to be signed next week. Indonesia, which ran a goods trade surplus of US$17.9 billion with the US in 2024 according to the US trade representative, is facing a 32% tariff in US markets and has proposed increasing US imports to facilitate trade talks between the two sides. Airlangga said the Indonesian government has offered to cut tariffs on key American exports, including agricultural products, to near-zero from between 0% and 5% at present. 'It will be near zero (tariffs for US main exports), but it will depend as well on how much the tariffs we get from the US,' Airlangga said. Garuda's CEO has said it is in discussions with US Boeing to buy up to 75 units of aircraft. Garuda group did not respond to requests for comment today. The wheat purchases are also part of next week's pact with US partners. The chairman of Indonesia's wheat flour mills association, Franciscus Welirang, said its 'members will purchase 2 million tonnes in total through tenders with a competitive price.' 'The point is all of the members will buy US wheat,' Welirang, who is also a director at Indofood, told Reuters. The US counterparts in the wheat deal include Cargill, Bunge Global, Pacificor, Archer-Daniels-Midland, Columbia Grain International and United Grain Corporation, Welirang added. US exports to Indonesia include soybeans, petroleum gases and aircraft, Indonesian government data showed. When asked whether the trade talks include military deals, Airlangga said they were 'not part of the negotiation'. Susiwijono Moegiarso, a senior official with Indonesia's coordinating ministry for economic affairs, told Reuters that in return, Jakarta has asked the US for preferential tariffs on its main exports, including electronics, textiles and footwear. 'We want them to lower the tariffs (for those goods) as low as possible,' he said. Indonesia has also offered the US opportunities to invest in critical minerals projects, including in the country's abundant resources of copper, nickel and bauxite.

Don't sideline locals in race for football glory, says Sarawak minister
Nine of Harimau Malaya's starting-11 in their 2027 Asian Cup qualifier against Vietnam last month were naturalised players. (Bernama pic) PETALING JAYA : Sarawak's sports minister has warned against having an overreliance on naturalised players in the Harimau Malaya squad, saying it could pose long-term risks to the growth of Malaysian football. While the rules under Fifa and the Football Association of Malaysia allow naturalised and heritage players to represent Malaysia, Abdul Karim Rahman Hamzah said he was concerned about the impact this would have on the development of local talent. He acknowledged that the trend was also visible regionally, with Vietnam, Indonesia and the Philippines adopting similar approaches as eligibility rules are relaxed, Dayak Daily reported. 'Personally, I prefer to see our 'anak jati', the natives, representing Malaysia and Sarawak. 'Many of those currently representing Malaysia are based in Europe or Latin America. It will be difficult for us to keep the local football scene alive if we continue relying on players from outside,' he was quoted as saying. Karim said focus should be placed on developing a strong and sustainable grassroots ecosystem. 'We have to keep on looking at ourselves and build it up from the bottom,' he said. Last month, a new-look Harimau Malaya eased past reigning Asean Cup champions Vietnam 4-0 at the Bukit Jalil National Stadium, their first victory against the Golden Star Warriors in 11 years. Nine of the team's starting-11 were naturalised players, with five of them – Joao Figueiredo, Rodrigo Holgado, Jon Irazabal, Facundo Garces and Imanol Machuca – receiving Fifa clearance just hours before kick-off. FAM's policy of naturalising foreign players for the national team came under scrutiny from former national players last year, who argued that the national football body should focus on developing local talent rather than relying on foreign-born players. Currently, footballers whose parents are Malaysian or were born in Malaysia are eligible to join the national squad.
