美国各地航空公司周六取消了数千个航班，因为它们正努力从前一天的全国性停飞中恢复，那次停飞让乘客争抢座位，并扰乱了全球旅行。
Airlines cancelled thousands of flights across the U.S. on Saturday as they worked to recover from a nationwide ground stop a day earlier that left passengers scrambling for seats and disrupted travel around the world.
联邦航空管理局（FAA）局长布莱恩·贝德福德周六在华盛顿特区告诉记者，美国航空旅行时间表预计将在周日结束前恢复正常，这距离25年来美国最长的一次全国性停飞已过去两天。
The U.S. air travel schedule should be back to normal by the end of Sunday, two days after what was the nation's longest ground stop in 25 years, Federal Aviation Administration (FAA) administrator Bryan Bedford told reporters in Washington, D.C., on Saturday.
他说，航空公司周六“仍将出现延误和取消”，但承诺“最糟糕的情况已经过去”。美国交通部长肖恩·达菲表示，问题始于承包商L3哈里斯技术公司在更换空管系统旧铜线为新光纤的过程中，以某种方式导致系统过载。
He said airlines "will still have delays and cancellations" Saturday but promised the "worst is behind us." U.S. Transportation Secretary Sean Duffy said the problem began when contractor L3Harris Technologies Inc. was replacing a section of the air traffic control system's old copper wire with new fibre wire, somehow causing the system to overload.
这项工作导致通信和雷达出现“间歇性”中断，促使联邦航空管理局关闭空中交通管制超过四小时。
The work led to "intermittent" communications and radar gaps, prompting the FAA to shut down air traffic for more than four hours.
达菲说，官员正在调查是承包商“无能”还是路由器故障导致了此事。
Duffy said officials were investigating whether contractor "incompetence" or a faulty router was the cause.
L3哈里斯表示，正在配合联邦航空管理局的调查，以“了解导致停飞的情况”。
L3Harris said it was supporting the FAA in its investigation to "understand the conditions" that led to the ground stop.
“L3哈里斯严肃对待此次全国性停飞及其对旅客、航空公司和空管运行的影响，”该公司在一份声明中说。
"L3Harris takes the nationwide ground stop and its impact on travelers, airlines and air traffic operations seriously," it said in a statement.
这是自2023年1月以来的首次全国性停飞，当时联邦航空管理局一个向飞行员发送通知的关键计算机系统发生故障，也是“9·11”袭击事件以来的第二次。
The nationwide stop was the first since January 2023, when a key FAA computer system that sends notices to pilots malfunctioned, and the second since the Sept. 11, 2001, attacks.
航空顾问安德鲁·查尔顿表示，周五的停飞影响了美国每天约4.5万个航班中的约四分之一。
Aviation consultant Andrew Charlton said Friday's stoppage affected about a quarter of the 45,000 flights that happen in the U.S. each day.
滞留的不列颠哥伦比亚省旅客因美国停飞令导致航班取消而损失数千元 蒙特利尔特鲁多机场称运营在逐步恢复正常“连锁反应令人难以置信。飞机并不是只从A点飞往B点再飞回来……然后就停了。它接着会飞往C点，再飞往E点，就这样绕来绕去、周而复始，”他说。
Stranded B.C. flyers out thousands amid flight cancellations due to U.S. ground stop Montreal Trudeau airport says operations gradually returning to normal after U.S. ground stop "The knock-on effect of that is incredible. The aircraft doesn't just fly from A to B and back … and then stop. It then moves onto C and then over to E and around and around and around," he said.
“如果涉及长途航班、跨大西洋或跨太平洋的国际航班，情况当然会更加严重。”“我只想回家”周六，美国各地机场的乘客仍在设法想办法抵达目的地。有人在酒店等待混乱局面结束，有人冲去抢租车、巴士或火车票。许多人被迫在机场露宿。
"It is, of course, exacerbated if you're talking about long-haul flights, international flights over the Atlantic or over the Pacific." 'I just want to go home' At airports across the U.S. on Saturday, passengers were still scrambling to figure out how to get to their destinations. Some waited out the chaos in hotels, others sprinted to snag rental cars and bus or train tickets. Many were forced to camp out in airports.
66岁的丹·拉塞尔得知他的转机航班取消时，距离原定在圣地亚哥登机的时间仅剩半小时，那是周五晚上。酒店客满，他和妻子只能在机场等待改签的航班，两人是从夏威夷返回。“毫无办法，”拉塞尔说，妻子玛丽试图靠在他的肩上小睡。
Dan Russell, 66, learned his connecting flight to Fresno, Calif., was cancelled a half-hour before boarding was scheduled in San Diego on Friday night. Hotels were full, so he and his wife, who were returning from Hawaii, waited at the airport for a rebooked flight. "There's nothing you can do," Russell said, as his wife Mary tried to nap on his shoulder.
在新泽西州纽瓦克自由国际机场，乌米·埃奇试图弄清自己的航班何时能衔接上，好让他返回日本家中。
At the Newark Liberty International Airport in New Jersey, Umi Egchi was trying to figure out when his flights would line up so he could return home to Japan.
“我不太清楚到底发生了什么。我只想回家，”埃奇说，他把眼罩推在头顶上。
"I'm not sure exactly what happened. I just want to go home," said Egchi, who had a sleep mask on top of his head.
航班追踪网站FlightAware称，周六在美国境内、飞往美国或从美国起飞的航班中，有超过5100班被取消。
FlightAware, a website that tracks flights, said more than 5,100 flights within, into or out of the U.S. had been cancelled Saturday.
官员坚称无人处于危险之中 杜菲周六重申，当时空中有超过3000个航班，它们都安全着陆了，无人处于危险之中。
Officials insist no one was in danger Duffy reiterated Saturday that no one was in danger as more than 3,000 flights in the air at the time of the grounding order landed safely.
特朗普政府官员还指责国会未能批准更多资金，以替换帮助管理美国空中交通的几十年老旧技术。达菲表示，该系统已有70%被光纤线替换，但其机构还需要新的空中交通管制塔和跑道。
Trump administration officials also blamed Congress for failing to approve more funding to replace the decades-old technology that helps manage U.S. air traffic. Duffy said 70 per cent of the system had been replaced with fibre optic wire but his agency also needs new air traffic control towers and runways.
联邦航空管理局已将数千条旧铜线替换为光纤线路，并升级了数百套无线电系统，这是去年国会批准125亿美元资金后启动的一项大修计划的一部分。达菲和白宫正在争取再拨款300亿美元以完成这项工作。
The FAA has replaced thousands of old copper wires with fibre optic lines and upgraded hundreds of radio systems as part of an overhaul that began last year after Congress approved $12.5 billion in funding. Duffy and the White House are pushing for $30 billion more to complete the work.
达菲表示：“整个空域都存在基础设施老化的问题，”同时强调飞行仍然安全。“如果我们认为你们无法安全到达，你们就到不了目的地。”达菲说，自停飞令生效以来，他已多次与美国总统唐纳德·特朗普通话，但总统对此事一直保持沉默。他未公开发声，也未通过社交媒体发表声明。他曾与一名福克斯新闻记者通电话，但那不是在镜头前。查尔顿指出了更新一个永远无法关机系统的困难。
"We have aging infrastructure throughout the airspace," Duffy said, while stressing that flying remains safe. "You won't get to your destination if we don't think you can get there safely." Duffy said he had repeatedly spoken with U.S. President Donald Trump since the ground stop began, but the president has been quiet on the topic. He has not spoken publicly nor issued statements via social media on the matter. He spoke on the phone with a Fox News reporter, but that was not on camera. Charlton pointed to the difficulties of updating a system that can never shut down.
航空顾问查尔顿说：“你们看到的这是在汽车以每小时80英里的速度在高速公路上行驶时试图给它换轮胎，因为航空领域没有什么会停下来。”
"What you're watching here is trying to change the tires of your car when the car's going at 80 m.p.h. down the expressway, because nothing stops in aviation," the aviation consultant said.
周五的问题似乎与去年9月发生的一次区域空中交通管制通信中断相似，那次故障导致美国东北部数百个航班受阻。那次中断与一支施工队切断一条光纤线路有关。
Past problems Friday's problem appeared similar to a regional air traffic control communication outage in September that snarled hundreds of flights across the U.S. Northeast. That disruption was linked to a construction crew cutting a fibre optic line.
老化设备也被归咎于去年导致纽瓦克机场受阻的几次短暂雷达中断。
Aging equipment was also blamed for brief radar outages last year that disrupted Newark airport.
航空安全专家史蒂夫·阿罗约表示，周五故障的不同之处在于中断的规模，这导致管制员无法可靠地与飞行员通话。
Aviation safety expert Steve Arroyo said the difference Friday was the scale of the disruption, which left controllers unable to reliably talk to pilots.
“如果你不具备那种能力……你就得把飞机留在地面上，别让它们升空，那样你会面临无法与它们通联的风险，”前联合航空飞行员阿罗约说。
"If you don't have that ability … you've got to stop airplanes on the ground and not put them in the air, where you're going to risk not being able to communicate with them," said Arroyo, a former United Airlines pilot.
