Duffy asks Congress for $50 billion to fix air traffic control, hours after a $30.1 billion request

Transportation Secretary Sean Duffy asked Congress on Friday night for $50 billion in emergency funding to rebuild the nation's air traffic control system, after a nationwide ground stop that lasted more than four hours. Speaking at a White House news conference, he blamed outdated switches and routers that were overloaded with data, and said the old equipment "is going to continue to fail," Fox Business reported. Our earlier story covers the stop itself. This one covers what the money ask means.

The number behind the number

The $50 billion is not the first figure on the table. AeroTime reported that earlier on Friday, before the outage surfaced, Duffy and White House budget director Russell Vought asked lawmakers for $30.1 billion for air traffic control and airport upgrades. That request included $10.1 billion for air traffic control modernization, $2 billion for control towers and $18 billion for airport projects, $10 billion of it for terminals. AeroTime says Duffy did not explain at the evening briefing how $50 billion related to the morning request.

Fox Business also reported that a roughly $5 billion contract awarded in April to Rohde & Schwarz USA covers up to 462 voice communication switches, with more than 40 installed so far, according to FLYING magazine. Federal officials say about half of the old copper wiring has been replaced.

What failed, so far

Duffy said aging routers became overloaded and fed inconsistent data to controllers. Homeland Security Secretary Markwayne Mullin said there was no evidence of a cyberattack and no link to the Microsoft outage a day earlier, and suggested new equipment and patches may have overwhelmed parts of the older network, per AeroTime. AeroTime adds that CBS News, citing multiple sources, reported an update triggered a reboot and crash on a private network run by L3Harris. The FAA has not publicly named the failed component, so treat the cause as unconfirmed. If an update caused it, that sits awkwardly beside the argument that only a complete replacement will fix it, and Congress is likely to ask which it was. Senate Commerce Committee Democrat Maria Cantwell said the panel is looking into the telecommunications problems.

Who it hits

• Airlines. Delta closed Friday at $86.25, before the stop, so Monday's open is the first market read. A new federal funding fight is a longer-term issue; Monday's trading will mostly turn on how many cancellations spill into the weekend.
• Travel-dependent small businesses. Freight forwarders, event vendors and shops near airports lose a day of revenue per canceled day. JetBlue said it would cancel the rest of Friday's flights, aside from European routes, and some Saturday departures, according to CNBC.
• Travelers this weekend. Cirium counted about 11,000 flights scheduled to leave after 4 PM ET, carrying 1.5 million passengers (CNBC). Recovery takes days, not hours, so check your airline's app and rebook early.

What to watch

Whether lawmakers treat the request as emergency spending or fold it into the existing bill, and whether the FAA names the root cause. Duffy faces congressional questioning, AeroTime reports.
