国土安全部部长马克韦恩·穆林强调，周五乘机出行的美国民众是安全的，同时表示国土安全部将继续追查导致政府下令停飞航班的电信中断事件的根本原因。
Homeland Security Secretary Markwayne Mullin stressed that Americans flying Friday are safe, even as he said the Department of Homeland Security (DHS) would continue to seek the root cause of a telecom outage that pushed the government to ground flights.
穆林在白宫外回答记者提问时说：“这是联邦航空局全系统的电信中断。”他指的是联邦航空管理局（FAA）。“截至目前，没有迹象表明这是针对我们的恶意攻击。目前这只是一起电信中断事件。”但在记者追问下，穆林表示该机构不会排除网络攻击的可能性。
“This was a telecommunication outage throughout FAA,” Mullin said while fielding questions outside the White House, referencing the Federal Aviation Administration. “There was no indication as of yet that this was a nefarious attack against us. It's just a telecommunication outage as of right now.”But pressed by reporters, Mullin said the agency would not rule out a cyberattack.
他对记者说：“当然，通过国土安全部，我们接到了大量电话，问：‘这是恐怖袭击吗？这是恐怖袭击吗？’大家都是安全的。如果亲人正在乘机或类似情况，没有理由担心。我只是想让大家对此放心。在我们调查造成此事的原因时，鉴于发生的众多网络攻击，你总得假设这是网络攻击。所以，但截至目前，这还不清楚。”
“Of course, through DHS, we're getting a ton of calls saying, ‘Is this a terrorist attack? Is this a terrorist attack?’ Everybody's safe. There is no reason to be concerned about your loved ones if they're flying or anything like that. I just want to make sure everybody's at ease about that. As we investigate what caused this, you always got to assume that as many cyberattacks that take place that you make that assumption. So, but as of right now, that's not known,” he told reporters.
他说：“我们将继续工作。首要任务是确保恢复通信，让所有航班落地，然后恢复正常运营。但我们将继续努力，查明根本原因。”
“We're going to continue to work. The first thing we want to do is make sure we restore the communications, we get all the flights on the ground, and then we get back normal operations. But we're going to continue to work to find out what the root of the cause is.”
