A man in East China's Jiangsu Province who recently tried to swim across the Yangtze River to Shanghai to save travel costs is rescued by police.

Police received a report around noon on August 4 that a man was swimming near a park, where heavy vessel traffic made the situation particularly dangerous. After a coordinated search by land and water, officers located the man, according to multiple media reports.
However, the man initially refused to board the police boat. Officers then learned that he intended to swim across the Yangtze River to Shanghai to avoid paying for transportation, according to Jiangsu TV.
The section of the Yangtze in Nantong is wide and has strong currents, while the main shipping channel is busy with passing vessels. The attempt posed serious risks not only to the man himself but also to the safety of vessels navigating the river, policemen said, per media reports.
After nearly 30 minutes of persuasion, the man finally abandoned his plan and boarded the police boat. He had by then spent about two hours in the water and was exhausted, suffering from severe leg cramps. Police officers provided him with food and water and took him to a police station to rest.
The police later identified the man as a native of Linyi, East China's Shandong Province, and found that he had a mental health condition. They contacted his family and the Nantong rescue center and arranged for him to undergo a psychiatric assessment.
His family subsequently took him back to Shandong and thanked the officers for rescuing him.

。与大多数机上Wi-Fi提供的典型速度相比，这当然是一个大飞跃。 OneZero报告说，大多数航班使用的是空对地系统，每架航班的最高速度约为10Mbps（而且只在陆地上空飞行时工作），而目前的卫星系统通常提供30Mbps至100Mbps速率。

三 | 据Aviacionline报道，在最近的一次测试飞行中，Starlink航空能够在机上提供100Mbps的互联网速度。JSX在伯班克和加州圣何塞之间的一次飞行中进行了演示，该公司在4月宣布它将成为首批采用机上互联网服务的航空公司之一。9月，JSX首席执行官Alex Wilcox说，他预计本月开始向乘客提供该服务，并在年底前让公司的每一架飞机都配备该系统，夏威夷航空公司也在4月宣布与Starlink达成协议，预计明年开始安装。SpaceX首席执行官埃隆·马斯克早就讨论过该公司为飞机提供Starlink互联网服务的计划。2021年3月，SpaceX向联邦通信委员会提出申请，授权Starlink在移动平台上使用。"这是针对飞机、船舶、大型卡车和房车的，"马斯克不久后在Twitter上说。
