What triggered Friday's nationwide FAA ground stop: failing old equipment, a bad software update, or an attack?
The FAA halted all U.S. departures for more than four hours on Friday after a communications failure at air traffic control centers, and thousands of flights were canceled or delayed.
The desk's odds on each answer
Answer
Odds
Failure or overload of aged communications equipment, with no outside triggerThis is the explanation officials have given so far, and it fits the 'legacy' and 'analogue' language.
42%
A software or configuration change caused the failureA reported FBI look at a software update points here, though it rests on one report with no named source.
38%
Something else, or a mix not captured aboveThe FAA has not named the trigger, so the evidence is thin and a combined cause is plausible.
14%
Cyberattack or deliberate sabotageOfficials deny it, but denials this early are not a final finding.
6%
What is known
The Guardian reports officials blamed the ageing air traffic control system; Nextgov says officials cited a legacy technology issue. (theguardian.com, nextgov.com)
Officials said there was no indication of a cyberattack or a link to the Microsoft outage earlier in the week. Homeland Security Secretary Markwayne Mullin said it was not a 'nefarious attack' and that there was 'zero evidence' of a cyberattack. (nextgov.com, dailycaller.com, marketwatch.com)
SecurityWeek reports the FBI is reportedly probing a software update as a possible cause. The row does not name the source of that report. (securityweek.com)
The FAA blamed a telecommunications issue affecting multiple air route traffic control centers. SOFREP says the FAA has not explained what triggered it. (fedscoop.com, sofrep.com)
ABC counts more than 12,500 flights canceled Friday and Saturday. Transportation Secretary Sean Duffy is asking for $50 billion and calling this an emergency. (abcnews.com, zerohedge.com)
What else has been going on
A Microsoft outage earlier in the week left some users without email for more than 24 hours; Microsoft says services are fully restored. Officials say the two events are not linked. (nextgov.com, globalnews.ca)
Reuters-sourced coverage calls this the longest U.S. air shutdown since the September 11, 2001 attacks. (khaosodenglish.com)
How questions like this usually turn out
Background knowledge: large aviation and IT outages have usually been traced to internal faults, such as equipment failure, configuration errors or bad updates, rather than hostile attacks. Full explanations often take weeks.
A caution on the coverage
Officials have reason to prefer the aging-system account, which also supports Duffy's $50 billion request. The software-update claim rests on a single report. First-day coverage focuses on delays, not on why the failure spread across multiple centers.
What would settle it
A formal FAA or Transportation Department incident explanation naming the failed system
An FBI or Homeland Security statement closing or confirming a software-update inquiry
Congressional testimony from FAA leaders on the cause
Will the U.S. carry out new military strikes on Iran in the next month?
Reuters, citing three unnamed people, reports Trump told advisers he may hold off attacking Iran if there are no new provocations, while Iran claims fresh attacks on U.S. assets and mine strikes on tankers.
The desk's odds on each answer
Answer
Odds
No new U.S. strikes on Iranian territory or forces by mid-DecemberTrump's reported stance and public remarks lean toward restraint, and regional allies are urging it.
55%
Limited U.S. retaliatory strikes on IranDrone shootdowns and the claimed Bahrain attack are provocations of the kind the reported condition refers to.
22%
U.S. strikes hit the Houthis but not IranThe reported condition names the Houthis, who are still firing at Saudi Arabia.
15%
A large-scale U.S. strike campaign resumesIt is possible given the volatility, but the stated direction is away from it.
8%
What is known
Reuters, citing three people familiar with the matter, says Trump told senior advisers he may hold off on attacks if Iran and the Houthis in Yemen provoke no further. (english.alarabiya.net, timesofisrael.com, ukrinform.net)
Current and former officials told Reuters Trump has alternated between threats of new strikes and winding down, and does not appear to have decided. (jpost.com)
Iran's IRGC says it shot down a 17th U.S. MQ-1 drone over Qeshm Island and destroyed a U.S. early-warning radar in Bahrain. Both are Iranian claims. (tass.com, en.irna.ir, al-monitor.com, newsnationnow.com)

The Saudi-led coalition says it intercepted two Houthi drones over Riyadh and southern regions. (freemalaysiatoday.com)
How questions like this usually turn out
Background knowledge: leaks about a leader's willingness to hold off often hold only while the other side avoids incidents. Pauses in this kind of conflict have often been broken by a single incident.
A caution on the coverage
The restraint report rests on unnamed sources and says Trump has not decided. Iran's claims on drones, the radar and the mines come from its own military. The U.S. has not confirmed them in these rows.
What would settle it
An announcement or confirmation of U.S. strikes from the Pentagon or White House
A formal U.S.-Iran de-escalation or talks announcement
Confirmation or denial of the Bahrain radar and drone losses by U.S. Central Command
What will come out of the planned Trump-Xi-Putin meeting in Shenzhen?
The White House and Kremlin say the leaders of the U.S., China and Russia will hold a first-ever three-way meeting on the sidelines of the APEC summit in Shenzhen on November 19.
The desk's odds on each answer
Answer
Odds
Meeting held, with no joint statement or agreementThere is no sign of staff-level work on a text, and the three governments have very different aims.
44%
Meeting held, with a joint statement or announced start of arms-control talksTrump has a stated arms-reduction goal, and a pledge to talk is a low bar.
32%
Meeting postponed, cancelled or not held with all three leaders in personBoth sides have confirmed, but this is a hastily announced summit in a volatile period.
12%
Something elseCovers outcomes such as a bilateral-only result or an announcement on Ukraine instead.

Trump's Asia trip also includes the Philippines, where an ASEAN summit is under way, and a Quad summit is likely in Manila on November 17. (washingtontimes.com, rappler.com, thehindu.com)
How questions like this usually turn out
Background knowledge: first-of-a-kind leader summits usually produce a statement or a promise to keep talking. Signed arms-control agreements usually follow long staff-level negotiation.
A caution on the coverage
The White House, Kremlin and Chinese side each have reason to describe the meeting as a success. The arms-control goal is reported as what Trump wants, not what Xi or Putin have agreed to. The rows do not show Chinese confirmation.
What would settle it
Joint or separate readouts from the White House, Kremlin and Chinese foreign ministry after November 19
Will Ukraine's government publicly accept withdrawing from any part of Donbas as part of a peace deal in the next month?
Zelensky says U.S. negotiators floated, for the first time, the idea of Ukraine withdrawing from Donbas in exchange for NATO membership, after the latest Abu Dhabi talks with Russia.
The desk's odds on each answer

Zelensky says SpaceX is restricting Ukraine's Starshield access over occupied territory. SpaceX denies it. (nytimes.com, themoscowtimes.com)
How questions like this usually turn out
Background knowledge: territorial concessions are the hardest issue in wars of this kind, and governments rarely accept them quickly after a first public mention. Trial ideas often fade.
A caution on the coverage
The Donbas-for-NATO account comes from Zelensky; the rows carry no U.S. statement on it. Kyiv has reason to publicize a proposal it opposes, and Washington may describe it differently. Coverage leaves out whether Russia would accept such a trade.
What would settle it
A U.S. or Russian statement confirming or denying the proposal
A referendum announcement from Kyiv
A signed ceasefire or framework document
The outcome of the Shenzhen meeting, if Ukraine is discussed
What caused the tanker Atlantic Asphalt to lose control and hit the docked cruise ship American Heritage in New Orleans?
A Marshall Islands-flagged asphalt tanker struck the docked riverboat American Heritage on the Mississippi in New Orleans on Friday, sinking it; all aboard survived.
The desk's odds on each answer
Answer
Odds
Propulsion or steering failure on the tanker'Lost control' language suggests an equipment problem, but it is only a headline.
42%
Navigation or vessel-handling error by the crew or pilotA common cause in river collisions, and nothing in the rows rules it out.
30%
A combination or another causeEvidence is thin, and investigators often find several contributing factors.
20%
River current or conditions as the main causeThe rows give no weather or current detail.
8%
What is known
The vessel was docked and operated by American Cruise Lines. gCaptain reports all passengers and crew survived. (dailymail.com, gcaptain.com)
An AP headline says the tanker 'lost control' before the collision. (apnews.com)
A portion of the Mississippi River remained closed after the collision. (france24.com)
What else has been going on
An earlier Coast Guard report said 195 people were accounted for, with numerous people missing at that point. Later reports say everyone was accounted for. (militarytimes.com, gcaptain.com)
How questions like this usually turn out
Background knowledge: ship collisions at docks are most often traced to loss of propulsion or steering, or to navigation or handling errors, and official findings usually take many months, with only a preliminary report in the first weeks.
A caution on the coverage
'Lost control' comes from a headline; the rows carry no official statement of cause. The ship's owner and the cruise line each have reason to prefer a cause that points to the other. Early coverage focused on the rescue.
What would settle it
A preliminary report from the National Transportation Safety Board or Coast Guard
A statement from the tanker's operator on what failed
Reopening notices that describe the cause
Expect to know: Preliminary findings in weeks; a full finding likely months later
