TAIPEI (AP) — A small aircraft crashed into Beijing’s tallest building on Friday, the global flight tracking service provider Flightradar24 confirmed, following witness accounts and evacuations in the city’s business district.In a social media post, Flightradar24 posted the flight path of the plane, a Sunward SA 60L Aurora, which took off from an airport about 50 kilometers (30 miles) east of Beijing. It headed westward and ended just east of the East Third Ring Road shortly before 6 p.m. in local time. The flight data provider said the plane crashed into the CITIC Tower, also known as China Zun, which rises more than 1,700 feet (528 meters), just east of a major ring road in a cluster of skyscrapers.The 108-story CITIC tower, shaped like an ancient Chinese wine vessel, is one of the most recognizable skyscrapers in Beijing.It wasn’t immediately known what caused the crash in a city with strict airspace controls, including a recent ban on drones. Information on the pilot also was not immediately available. There was no immediate information on whether there were any on-ground casualties.Chinese authorities have not issued a statement, nor has the crash been reported by state media. Social media posts about the crash have been scrubbed from China’s walled-off internet, though footage has made its way outside of China’s firewall and is circulating on overseas sites such as X.com.
