(WASHINGTON, D.C.) A transatlantic United Airlines flight returned to Washington after a passenger’s laptop slipped into a hidden gap and fell into the cargo hold, forcing pilots to turn back because of a possible fire risk from the device’s lithium‑ion battery. The United Airlines flight left Washington Dulles International Airport on October 15, 2025, bound for Rome, but made a U‑turn over the Atlantic near Boston less than an hour into what was planned as an eight‑hour journey.
What happened on the Dulles–Rome flight

According to the airline, a passenger dropped a laptop down the side of their seat. Instead of stopping under the seat, the device slid through an unusual gap in the cabin wall and disappeared into the cargo area below.
Because the laptop was still powered on and contained a lithium‑ion battery, crew members and ground experts treated the situation as a serious safety threat. The cargo hold on this particular aircraft—a Boeing 767—did not have a dedicated fire suppression system for that area, increasing concern about how quickly any fire could be detected and contained.
Pilots followed standard safety procedures that favor landing as soon as practical when there is a credible fire risk, and they chose to abandon the eastbound route and return to Washington. The flight landed safely back at Dulles, where maintenance crews accessed the cargo hold and recovered the laptop.
After checks and clearance, the aircraft departed again for Rome, ultimately reaching its destination with a delay of about four hours for passengers who had already spent part of their night in the air.
A second similar diversion: London–Washington
A separate United Airlines flight on a different route also had to change course over the Atlantic for a similar reason. That aircraft, traveling from London to Washington, D.C., experienced another incident in which a passenger’s laptop became stuck in a way that raised safety concerns.
In that case, the plane diverted to Dublin, producing about five hours of delay before the journey could continue. Together, the two events show how a dropped laptop can turn into a major operational issue when it ends up in a sensitive or inaccessible part of the aircraft cabin.
Quick comparison of the two incidents
| Incident | Route | Aircraft | Diversion/Return | Reported delay |
|---|---|---|---|---|
| Dulles → Rome | Washington–Rome | Boeing 767 | Returned to Washington (Dulles) | ~4 hours |
| London → Washington | London–Washington, D.C. | Not specified | Diverted to Dublin | ~5 hours |
Why lithium‑ion batteries matter
- Lithium‑ion batteries power most modern laptops, phones, and tablets.
- While normally safe, they can overheat, swell, or catch fire if damaged, crushed, or exposed to certain conditions.
- When a device is trapped in a place where crew cannot easily see or reach it, the risk becomes more serious.
- If smoke or flames start in an inaccessible area—behind a panel or inside cargo space—it may take longer to respond, which is dangerous at high altitude.
Regulatory guidance and airline practice
Airlines and regulators have worked for years on rules for electronic devices and batteries on planes, especially on long‑haul international routes like Washington–Rome or London–Washington.
- Most airlines now require spare lithium‑ion batteries and power banks to be carried in carry‑on baggage, not checked luggage.
- If a problem occurs in the cabin, flight attendants can use fire‑resistant bags, water, or other tools to control it.
- A battery hidden in the cargo hold is far harder to reach and mitigate.
The Federal Aviation Administration in the 🇺🇸 United States publishes safety guidance for passengers about lithium batteries and electronic devices on aircraft, including basic rules for traveling with laptops and other gear in checked and cabin bags, on its official website at faa.gov.
Passenger and immigration impacts
The timing and location of such turnbacks or diversions can have outsized effects on international travelers:
- For passengers on the Dulles–Rome flight, the aircraft turned back near Boston less than an hour after departure, leading to a long night and missed connections in Europe.
- For some travelers, a four‑hour delay may only mean a later hotel check‑in.
- For others—those heading to visa interviews, starting new jobs abroad, or facing immigration deadlines—such delays can add serious stress.
According to analysis by VisaVerge.com, flight disruptions on long‑haul routes often hit international travelers with complex schedules hardest, because they may have multiple bookings and legal time limits tied to their trips.
Aircraft design and safety review implications
The unusual design gap in the cabin wall that allowed a laptop to fall into the cargo hold is drawing attention.
- The source material does not describe the exact cause of the gap, but the fact that an object as large as a laptop could pass through it into a sensitive area raises questions about cabin fittings and seat layouts.
- For airlines operating older wide‑body aircraft like the Boeing 767, incidents like this may prompt closer checks around premium cabins or bulkhead areas to ensure similar openings are sealed or redesigned.
Crew decision‑making and safety culture
For crew members, these incidents highlight the tension between keeping flights on schedule and treating every potential fire risk with maximum caution.
- Once cabin crew on the Rome‑bound flight learned a powered laptop with a lithium‑ion battery had dropped into an inaccessible cargo space without fire suppression, options became limited.
- Continuing across the ocean with that unknown risk on board would conflict with modern safety culture, which encourages pilots to err on the side of caution, even when it causes major disruption for passengers.
Key takeaway: When there is a credible fire risk—especially from lithium‑ion batteries in inaccessible spaces—airlines and crews prioritize immediate safety over schedule, even at the cost of significant delays.
Practical advice for passengers
These events are a reminder to be careful with electronic devices during takeoff, landing, and seat adjustments. Small precautions can prevent large disruptions:
- Keep laptops and spare batteries in secure carry‑on compartments.
- Use seat pockets or stable surfaces rather than loose storage between cushions.
- Check how power cords run and secure them during adjustments.
- Alert crew immediately if a device slips out of sight.
🔔 If a device slips from sight or seems to be stuck, alert flight crew immediately. Prompt reporting helps crews assess risk quickly and decide on the safest course of action for all aboard.
On crowded international flights linking hubs like London and Washington, a single misplaced laptop can affect hundreds of people, including tourists and new immigrants.
Wider implications for airlines and travelers
While both United flights eventually reached their destinations safely, the diversions added hours of delay, extra fuel burn, and scheduling challenges for the airline. They also increased stress for travelers trying to meet work meetings, transit visa requirements, or tight connection windows.
As more people carry multiple devices with lithium‑ion batteries, airlines are likely to keep focusing on this risk—even when the initial event seems as ordinary as a passenger adjusting their seat and losing grip of a laptop.
A United Airlines flight from Washington Dulles to Rome returned less than an hour after departure when a passenger’s powered laptop slid through an unusual cabin gap into the cargo hold. With the device containing a lithium‑ion battery and no dedicated fire suppression below, pilots prioritized safety and landed at Dulles. Crews recovered the laptop and, after checks, the plane resumed its journey, arriving about four hours late; a separate London–Washington flight diverted to Dublin for a similar reason.
