一 | (ECNS) -- An AI-powered “flying life ring” capable of autonomously reaching people in the water, keeping them afloat and returning to shore was demonstrated Aug. 6 at Xianghu Lake in Hangzhou, Zhejiang Province. Chinese Foreign Ministry spokesperson Lin Jian recently shared footage of the device on social media, calling it technology that could help save lives. During the drill, the orange ring flew from shore to a person in the water, shut down its propellers after landing, provided buoyancy, then took off again and returned to its starting point. Developed by Hangzhou police, the device uses autonomous navigation. Other equipment demonstrated included drones that can drop inflatable life rings and an unmanned rescue boat that works with a drone to locate and bring people back to shore. Hangzhou police said the technologies are intended to shorten critical response times in water emergencies.

"They tried to wipe out families and children.""The artifacts are bearing witness to things that we don't have in our history books," she added.Tiffany Crutcher, an activist, said she's been working to raise awareness of what happened and fight for justice. She has traveled to Congress with survivors and their families on multiple occasions to ensure that their stories are never forgotten."They sat there saying, 'We believe we deserve justice. We still believe in America,' even though they've been through the worst times," Crutcher said.In July, an Oklahoma judge dismissed a lawsuit filed by survivors and their families that sought reparations for the massacre. The decision has been appealed by the plaintiff's attorneys.After last week's passing of Hughes Van Ellis at 102, Lessie Benningfield "Mother" Randle, and Viola Fletcher, 109, are now the last of two living survivors.Lawanna Penny, Randle's granddaughter, said she promised her grandmother that even though the reparations suit has been dismissed, she and others wouldn't stop fighting for justice."I told her, 'We're not going anywhere,' she said. "We want to leave a legacy for her to build up North Tulsa, build it up back the way it used to be."Randle turns 109 next month and she told GMA 3 that she has one wish."I would like to see all of my people here…trying to make the situation better," she said. "Bring some of those things to life so people will know that it's really is true, because there's room for a lot more improvement."。
