美国运输部周六正在努力查明周五空管系统瘫痪究竟是人为失误还是设备故障所致，与此同时，全国各地的旅客仍在应对由此引发的连锁航班延误和取消。
The U.S. Department of Transportation was working Saturday to determine whether Friday's air traffic control system meltdown resulted from human error or equipment failure as travelers across the nation continued to grapple with a cascade of flight delays and cancellations.
运输部长肖恩·达菲表示，事发时一名承包商正在联邦航空管理局（FAA）的一个偏远设施进行例行维护，将电信线路从20世纪80年代的铜线更换为光纤线路。他说，新设备开始向空管系统中的其他路由器发送海量数据——每四到五秒发出超过1000次连接尝试——导致雷达和通信中断。作为安全措施，联邦航空管理局决定停飞所有航班，持续了四个多小时。目前尚不清楚是承包商L3Harris Technologies（L3哈里斯科技公司）还是新设备本身出了问题。
Transportation Secretary Sean Duffy said the crisis began when a contractor was performing routine maintenance at a remote Federal Aviation Administration location to switch telecommunication lines from 1980s-era copper wire to a fiber line. The new equipment began flooding other routers in the air traffic control system — sending more than 1,000 connection attempts every four to five seconds — causing radar and communications disruptions, he said. As a safety measure, the FAA decided to ground all planes for more than four hours. It is unclear whether the contractor, L3Harris Technologies, or the piece of new equipment itself was at fault.
达菲说：“这是一个未能应对挑战的FAA系统。承包商未能应对挑战，或者设备未能应对挑战——导致了系统瘫痪。”
“This was an FAA system that didn't meet the moment," said Duffy. "A contractor didn't meet the moment or the equipment didn’t meet the moment — and it caused the outages.”
L3Harris的一位发言人表示，公司正在配合FAA的调查，以了解导致停飞令的具体情况。L3Harris称，安全和可靠性是其最高优先事项，并郑重对待周五事故对旅客、航空公司和空管运行造成的影响。
A spokesperson for L3Harris said the company is supporting the FAA in its investigation to understand the conditions that led to the ground stop. L3Harris said that safety and reliability are its highest priorities and that it takes seriously the impact of Friday's incident on travelers, airlines and air traffic operations.
FAA局长布莱恩·贝德福德表示，他希望航空公司能在周日下班前恢复正常航班时刻表。贝德福德说，没有证据表明周五的系统故障是由人工智能或任何恶意行为者造成的。他为FAA决定停飞航班给受影响乘客带来的不便道歉，并强调危机期间没有人员伤亡。
FAA Administrator Brian Bedford said he is hopeful airlines will be able to resume normal flight schedules by close of business Sunday. There is no evidence that Friday's system failure was caused by AI or any nefarious actors, Bedford said. He apologized to passengers affected by the FAA's decision to ground flights and emphasized that no lives were harmed during the crisis.
他说：“很抱歉让你们经历这些，但我们这么做是出于正确的理由。”
"I'm sorry that we put you through this, but we did it for the right reasons," he said.
达菲表示，此次停飞凸显了继续现代化联邦航空管理局（FAA）“极其陈旧”电信系统的必要性。他称，目前该系统约70%已迁移至光纤网络，但其余部分仍依赖铜线。达菲感谢特朗普总统通过其2025年《宏伟美好法案》为交通部争取到了125亿美元投资，并呼吁国会批准额外300亿美元资金请求，以继续现代化国家航空基础设施。
Duffy said the ground stop highlighted the need to continue modernizing the FAA's "incredibly old" telecommunication system. Currently, around 70% of the system has been moved to a fiber network, but the remainder relies on copper wire, he said. Duffy thanked President Trump for securing a $12.5-billion investment in the Transportation Department through his 2025 Big Beautiful Bill Act and called on Congress to approve an additional $30-billion funding request to continue modernizing the nation's aviation infrastructure.
部分民主党籍国会议员对追加资金的需求提出质疑，指出仅有一部分获批用于升级空管系统的125亿美元已被支出。“十五个月后，政府仅承诺拨付43亿美元，实际支出仅10亿美元，留下80亿美元未承诺拨付、110亿美元未支出，”众议员里克·拉森（民主党-华盛顿州）和安德烈·卡森（民主党-印第安纳州）在一份联合声明中说。“请再次向国会解释，为什么还需要更多钱？”
Some Democratic members of Congress questioned the demand for additional money, pointing out that only a portion of the $12.5 billion approved to upgrade the air traffic control system has been spent. “Fifteen months later, the administration’s obligated $4.3 billion but only spent $1 billion, leaving $8 billion unobligated and $11 billion unspent,” Reps. Rick Larsen (D-Wash.) and André Carson (D-Ind.) said in a joint statement. “Explain to Congress, again, why they need more money?”
周六上午，数千架飞机重返美国领空，但航空公司警告恢复正常将需要数天，并敦促乘客在可能的情况下将航班改至较晚日期。贝德福德表示，联邦航空管理局预计，美国周六计划的4.1万个航班中，将有4000至5000个被取消。据航班追踪网站FlightAware数据，周五美国境内、进出港航班延误超过7400起，取消超过9000起。
On Saturday morning, thousands of planes were back in American airspace, but airlines warned it would take several days to recover and urged passengers to change their flights to later dates where possible. The FAA anticipates that 4,000 to 5,000 of the 41,000 flights scheduled in the U.S. on Saturday would be canceled, Bedford said. On Friday, there were more than 7,400 flight delays within, into or out of the United States and more than 9,000 cancellations, according to flight-tracking website FlightAware.
莱斯·罗德里格斯原定周五晚6点30分从洛杉矶飞往圣安东尼奥的航班是被迫停飞的数千个航班之一。她和妹妹被改签到周六上午的航班，但该航班延误，导致她们在机场等待数小时，希望能最终登机。“我们只能靠极大的耐心了，”罗德里格斯说。
Leis Rodriguez’s flight from LAX to San Antonio scheduled at 6:30 p.m. Friday was among the thousands that were grounded. She and her sister were rebooked for a Saturday morning flight, but it was delayed, leaving them to sit for hours in the airport hoping they'd be able to board at some point. "We have to rely on a lot of patience,” Rodriguez said.
“不知航班是否会取消让人焦虑。”尽管面临不便和不确定性，她仍为政府周五采取行动、停飞航班感到庆幸。“安全至上，我宁愿经历这种情况，也不愿承担任何巨大的安全风险，”她说。
“Not knowing if your flight is going to be canceled is anxiety-producing.”Despite the inconvenience and uncertainty, she’s glad the government took action and grounded flights Friday. “Safety is paramount, and I’d rather have this experience than have any kind of huge safety risk,” she said.
耶稣基督后期圣徒教会的传教士、尼拉·巴特勒修女和扎卡里·伍兹长老周五在墨尔本机场停机坪上得知美国航班停飞的消息。他们最终抵达洛杉矶国际机场（LAX），但分别错过了飞往阿尔伯塔和西雅图的转机航班。周六上午，这两名20岁的年轻人佩戴着教会姓名牌，提着行李站在数百名希望改签航班的人群排成的长队中。“光是困惑就够受的了，完全不知道身在何处，该排哪个队，”伍兹说。
Sister Nyla Butler and Elder Zachary Woods, both missionaries with the Church of Jesus Christ of Latter-day Saints, were on the tarmac Friday in Melbourne when they got word of flights being grounded in the U.S. They eventually made it to LAX, but missed their connecting flights home to Alberta and Seattle, respectively. On Saturday morning, the 20-year-olds wore their church name tags as they stood with their luggage in a line of hundreds of people hoping to rebook flights. “There’s just been a lot of confusion, having no idea where we are, what line we’re supposed to be in,” Woods said.
与此同时，薇薇·张垂头丧气地坐在靠近漫长值机排队处的窗台上，身边放着行李。她原定上午7点飞往卡尔加里的航班被取消，下一个可用航班要等到周日。她说，航空公司工作人员缺乏支持让她感到沮丧。“没有食物，没有酒店住宿券，什么都没有，”她说，“他们只说，‘不是我们的错。’” 此次停飞引发了尖锐的政治舆论，批评白宫官员最初缺乏清晰沟通，以及一次常规升级为何会造成如此大规模的中断。
Vivi Zhang, meanwhile, sat despondently with her luggage on a windowsill near a lengthy check-in line. Her 7 a.m. flight to Calgary was canceled, and the next available flight is Sunday. She said she was frustrated by the lack of support from airline staff. “No food, no hotel voucher, anything," she said. "They just said, ‘Not our fault.’”The ground stop sparked barbed political discourse over the initial lack of clear communication from White House officials and how a routine upgrade could generate such a massive disruption.
“交通和国土安全领导人迟迟未提供最新情况，等他们开口时，既没有关于发生了什么的合理解释，也没有说明是否会再次发生，”众议员乔治·怀特赛德斯（民主党-阿瓜杜尔塞）周五晚间在X平台发布的声明中表示。
"The Transportation and Homeland Security leaders were slow to provide updates, and when they did speak, they didn't have good explanations about what was happening, nor whether it would happen again," Rep. George Whitesides (D-Agua Dulce) said in a Friday evening statement on X. Whitesides, who was himself stuck in an airport for seven hours Friday, criticized the president for installing a Transportation secretary with "basically no professional transportation experience in one of the most crucial jobs we have as a country."
怀特赛兹本人周五在机场滞留了七个小时，他批评总统任命了一位“在国家最关键的职位之一上基本没有专业交通经验”的交通部长。达菲曾是体育电视节目主持人、检察官、国会议员和CNN政治评论员。纽约州州长凯西·霍楚尔呼吁达菲辞职，或由特朗普将其免职。她在周六的一份声明中说：“从长期的空管人员短缺到反复出现的通讯故障，我们航空系统的严重失误已在肖恩·达菲任内形成了一种模式。在所有这些问题面前，他更专注于在自己的真人秀节目中担任主角，而不是解决其机构面临的危机。”
Duffy is a former sports television personality, prosecutor, Congress member and CNN political contributor. New York Gov. Kathy Hochul called on Duffy to resign or Trump to remove him from his post. "From chronic air traffic controller shortages to repeated communications breakdowns, serious lapses in our aviation system have become a pattern on Sean Duffy’s watch," she said in a statement Saturday. "Through it all, he’s been more focused on starring in his own reality show than addressing the crisis at his agency."
前交通部长皮特·布蒂吉格质疑，为何一次孤立的设备故障会导致国家空管系统出现如此持续的大规模中断。他在周五表示：“系统中有许多冗余设计，因此通常情况下，如果有一个故障点，其他系统可以接管。”他指出，2023年他在任部长期间系统崩溃时，中断时间较短，仅持续约90分钟。他解释说：“实际上有四个不同的系统，其中一个瘫痪了，另一个可以上线接管，所以我不清楚为何这种冗余机制未能防止此次故障在范围和持续时间上造成如此大规模的中断。”
Former Transportation Secretary Pete Buttigieg questioned why an isolated equipment failure resulted in such a sustained disruption of the nation's air traffic control system. "The system has many redundancies in it so that normally, if there's one point of failure, something else can catch it," he said Friday, noting that when a system crashed under his tenure as secretary in 2023, the outage was shorter, lasting around 90 minutes. "There were actually four different systems, and one of them went out, and another one could be brought online to cover," he explained, "so it is not clear to me why that redundancy did not prevent an outage of this magnitude in terms of the scope and duration."
特朗普向来不回避聚光灯，但周五对这场前所未有的电信中断未发表评论。周五晚间的新闻发布会上，当被问及总统为何保持沉默时，达菲表示特朗普在“幕后全程参与”。周六，特朗普在社交媒体上转发了参议员约翰·肯尼迪（共和党-路易斯安那州）的一段言论，详述了该议员的政治优先事项，包括争取民主党对一项联邦航空管理局拨款法案的支持。
Trump, who rarely shies away from the spotlight, did not comment on the unprecedented telecommunications outage Friday. When asked about the president's silence at a Friday evening news conference, Duffy said that Trump was "fully engaged" behind the scenes. On Saturday, Trump posted a quote from Sen. John Kennedy (R-La.) on social media that detailed the legislator's political priorities, including getting Democrats' support on an FAA funding bill.
早些时候，达菲呼吁民主党人和共和党人团结一致，批准资金以完成联邦航空管理局空中交通管制网络的现代化改造，并升级全美各地机场的其他老化基础设施，如塔台和跑道。
Earlier in the day, Duffy called on Democrats and Republicans to unite and approve funding to finish modernizing the FAA's air traffic control network and upgrade other aging infrastructure, such as towers and tarmac, at airports across the United States.
