美国联邦航空管理局（FAA）周五下午因“特殊情况”下令全国所有航班停飞，这是自“9·11”袭击事件以来第二次实施全国性停飞。官员称，原因是区域空中交通管制中心出现通信问题。
The Federal Aviation Administration grounded all flights nationwide Friday afternoon for just the second time since the 9/11 attacks, as officials cited "extraordinary circumstances" caused by communications problems at regional air traffic control centers.
国土安全部部长将问题归因于电信中断，并表示目前没有迹象显示这是蓄意行为。后果深远，可能扰乱数千个计划航班，至少持续到周五深夜，打乱乘客出行计划。
The nation's top homeland security official attributed the problem to a telecommunications outage and said there was no indication yet of a nefarious act. The consequences were profound, disrupting potentially thousands of planned flights through at least late Friday night and upending travel plans for passengers.
“这令人沮丧。这听起来肯定不只是寻常的延误。我期待查明原因，”杰夫·杜布纳说。这位华盛顿律师乘坐的阿拉斯加航空航班原定从洛杉矶飞往华盛顿，已晚点半小时并正滑行至跑道，飞机随即停下。
"It’s frustrating. This certainly sounds like it’s going to be more than the usual run-of-the-mill delay. I look forward to finding out why," said Jeff Dubner, a Washington attorney whose Alaska Airlines flight home from Los Angeles was already half an hour late and taxiing to the runway when the plane came to a halt.
全国性停飞令是自2023年1月以来首次，当时FAA关键计算机系统故障；也是“9·11”袭击事件后第二次。
The nationwide ground stop was the first since January 2023 , when a key FAA computer system malfunctioned, and the second since the aftermath of the Sept. 11, 2001, attacks.
据FAA通报，实施限制系“因特殊情况及安全原因”。交通部长肖恩·达菲称，该机构正在调查影响全美22个区域空管中心的通信问题，这些中心负责指挥机场间的航路飞行。
Friday's restrictions were imposed "due to extraordinary circumstances and for reasons of safety," according to an FAA notice. The agency was investigating a communication issue affecting the 22 regional air traffic control centers that direct planes en route between airports nationwide, said Transportation Secretary Sean Duffy.
据国土安全部部长马克韦恩·马林称，国际航班按个案处理，周五晚间已有部分起飞。阿拉斯加航空表示，阿拉斯加州和夏威夷州内部航班部分未受影响。
International flights were being handled on a case-by-case basis, according to Homeland Security Secretary Markwayne Mullin, with some seen taking off Friday evening. Meanwhile, some flights within Alaska and Hawaii were not impacted, Alaska Airlines said.
高官称暂无蓄意行为迹象 马林在白宫告诉记者，目前没有迹象表明“这是针对我们的蓄意攻击。目前只是电信中断。” “大家都安全。如果亲人正在乘机，没有理由担心，”马林说。
Top official says no sign yet of nefarious act Mullin told reporters at the White House that there was no indication yet that "this was a nefarious attack against us. It's just a telecommunications outage as of right now." "Everybody's safe. There's no reason to be concerned about your loved ones if they're flying," Mullin said.
截至目前，至少有827个航班被迫改道。根据航空分析公司Cirium的数据，截至美国东部时间下午7点05分，其中670个航班被送回原出发机场，157个航班被改飞至其他机场。
At least 827 flights have been diverted so far as a result. As of 7:05 p.m. EST, 670 flights were sent back to the airport from where they originally took off, while 157 were redirected to a different airport, according to Cirium, an aviation analytics company.
许多航班改飞的机场包括华盛顿杜勒斯国际机场、洛杉矶国际机场、辛辛那提/北肯塔基国际机场和纳什维尔国际机场。
The airports where many of the flights ended up being diverted included Washington Dulles International Airport, Los Angeles International Airport, Cincinnati/Northern Kentucky International Airport and Nashville International Airport.
美国东部时间下午4点后，美国机场计划起飞约1.1万个航班，搭载超过150万名乘客，这增加了更多航班取消和改道的可能性。联合航空和美国航空表示，已经在空中的航班将继续飞行。
Some 11,000 flights carrying more than 1.5 million passengers were scheduled to take off from airports in the US after 4 p.m. EST, raising the likelihood of more cancelations and flight diversions.
美国航空在社交平台上发布声明称：“当联邦航空管理局解除这项全国性地面停飞令时，美国航空将全员出动，让乘客尽快踏上旅程。”
United Airlines and American Airlines said flights already in the air will continue.
周五下午，在芝加哥奥黑尔国际机场，过安检的旅客抬头看到屏幕上显示全线航班延误，得知了地面停飞的消息。
"It will be all hands on deck across American to get customers on their way as soon as possible when the FAA lifts this nationwide ground stop," American said in a statement on the social platform At Chicago O’Hare Airport on Friday afternoon, travelers passing through security learned about the ground stop when they looked up at screens that showed flight delays across the board.
一些人给亲友打电话，商量是留宿芝加哥一晚，还是另想办法前往目的地。
Some called friends or family members, debating whether to stay the night in Chicago or find another way to their destinations.
27岁的Amber McQuilkin坐在长椅上，失望地表示可能错过与朋友前往纽约观看《英雄联盟》全球总决赛的行程。她说朋友们已经抵达纽约。
Amber McQuilkin, 27, sat on a bench, disappointed that she might miss a trip with friends to New York for the League of Legends world finals. Her friends, she said, had already arrived there.
“几乎没有任何信息传达给我，”这位请了一周假出行的西雅图软件工程师说，“我一度想直接放弃航班改开车去，但越想越觉得那会很惨。”
"There’s not really any information being passed to me," said the Seattle software engineer, who took a week of vacation for the trip. "I contemplated just abandoning the flight and driving, but then the more I thought about it, the more I’m like, that would be miserable." Austin Curtis and his wife were rethinking their trip from South Bend, Indiana, to a friend’s baby shower in Denver after getting delayed during a layover in Chicago.
Austin Curtis和妻子原本计划从印第安纳州南本德经芝加哥中转前往丹佛参加朋友的宝宝洗礼派对，因中转延误，两人正在重新考虑行程。
They had boarded a flight to Denver from O’Hare International Airport when they were told to get off the plane.
他们已从奥黑尔国际机场登上飞往丹佛的航班，随后被告知下飞机。
"We did see them taking luggage off our plane and others, so we’re assuming it’s going to be a pretty substantial delay," Curtis said.
“我们确实看到他们正在从我们的飞机和其他飞机上卸下行李，所以我们推测延误会相当长，”柯蒂斯说。
They were unsure whether to get a hotel room or keep waiting out the delay at the airport. With care already in place for their two young children at home, they might stay the weekend in Chicago, he said.
他们不确定是该订酒店，还是继续在机场等待。他说，家里已安排好人照顾两个年幼的孩子，他们可能会在芝加哥待上周末。
Sports teams stranded and cargo flights delayed NBA, NHL and college teams were left stranded as they tried to reach their destinations. Meanwhile, NFL teams were left to wonder whether the issue would be resolved in time to travel to their games this weekend.
体育队伍滞留、货运航班延误 NBA、NHL和大学球队在试图抵达目的地时被困。与此同时，NFL球队只能猜测问题是否能及时解决，以便本周末前往比赛地。货运航班也因停飞令而延误。
Cargo flights were also delayed by the ground stop.

Despite the nationwide FAA ground stop, SpaceX launched its Starship rocket from Texas on Friday afternoon on its latest test flight.
政府一直在致力于改造过时技术 目前尚无恢复航班的时间表。穆林表示，调查人员将查明是否与联邦航空管理局全国推行的新人工智能系统有关，该系统用于帮助识别问题并重新规划航线。但该系统在华盛顿特区附近的一个地点运行，仅向空管中心发送建议。
The government has been working to overhaul outdated technology There is no timeline for restarting flights. Mullin said investigators will look at whether there is any link to the FAA's nationwide rollout of a new artificial intelligence system to help identify problems and reroute planes. But that system operates out of one location near Washington, D.C., and just sends recommendations to the air traffic control centers.
自国会去年批准125亿美元用于该项目以来，政府一直在致力于改造空管员赖以工作的过时技术。数英里旧铜线已被光纤取代，全国各地机场的旧无线电系统也在逐步更换。
The government has been working to overhaul the outdated technology that air traffic controllers rely on since Congress approved $12.5 billion for the project last year. Miles of old copper wires have been replaced with fiber optic lines and old radio systems are gradually being replaced at airports across the country.
但仍有大量工作要做。达菲表示，还需要300亿美元才能完成这项工作，白宫已开始游说国会批准这笔资金。
But much work remains. Duffy has said that another $30 billion will be needed to complete the work, and the White House has begun lobbying Congress to approve it.
航空安全专家史蒂夫·阿罗约表示，这个问题似乎与9月发生的一次区域性空中交通管制通信中断相似，那次中断导致美国东北部数百个航班受阻，只不过这次是全国范围的。这可能与空中交通管制员使用的过时技术有关。
The problem appeared similar to a regional air traffic control communication outage in September that snarled hundreds of flights across the Northeast, aviation safety expert Steve Arroyo said, except this time on a nationwide scale. It may be linked to the outdated technology used by air traffic controllers.
阿罗约曾是联合航空飞行员，他说：“如果你没有那种能力，无论是因为他们现有的旧线路已经破旧不堪，还是其他什么原因，你都必须让飞机停在地面上，而不能让它们升空，在那里你将面临无法与它们通信的风险。”阿罗约表示，周五的停飞与9·11事件后的停飞不同，当时飞机没有被要求立即降落，飞行员很可能能够与机场的地面管制员通信。
"If you don’t have that ability, whether it’s because the old wires that they have are just run down or for whatever reason, you’ve got to stop airplanes on the ground," said Arroyo, who is a former United Airlines pilot. "And not put them in the air where you’re going to risk not being able to communicate with them." Friday’s ground stop was different than the one after Sept. 11 because planes were not being told to land immediately and pilots likely were able to communicate with ground controllers at airports, Arroyo said.
