A major U.S. airport experienced its fourth serious near-miss incident in recent months on Wednesday, when a commercial jet was forced to brake hard on the runway to avoid a potential collision with another aircraft. The incident, which occurred during peak afternoon traffic, has reignited concerns over air traffic control staffing shortages and runway safety procedures at one of the nation’s busiest travel hubs. No injuries were reported, but federal investigators have already launched a probe into the event, which the National Transportation Safety Board (NTSB) classified as a serious runway incursion.
**Context**
The latest incident took place at approximately 2:45 p.m. local time at Chicago O’Hare International Airport, a facility that handles over 70 million passengers annually. According to preliminary reports from the Federal Aviation Administration (FAA), a regional jet operated by a major U.S. carrier was cleared for takeoff on Runway 27L. As the aircraft began its acceleration roll, air traffic controllers detected an unauthorized vehicle—believed to be a ground service truck—crossing the same runway without clearance. The controller issued an immediate abort command, and the jet’s pilot engaged the brakes at high speed, bringing the aircraft to a stop within several hundred feet. The truck, which was reportedly carrying baggage equipment, cleared the runway moments before the jet reached its position.
This incident marks the fourth such near-miss at O’Hare since June. In July, a Delta Air Lines flight was forced to abort its landing after a private plane entered the runway without authorization. In August, a United Airlines jet came within 200 feet of colliding with a maintenance vehicle during taxi. In September, an American Airlines flight narrowly avoided a ground vehicle during its landing roll. The FAA has confirmed that all four incidents are under investigation, and the agency has temporarily reassigned several air traffic controllers at the O’Hare tower for retraining.
The NTSB has noted that runway incursions—defined as any unauthorized presence on a runway—have been on the rise nationally. In 2025, the FAA reported over 1,700 runway incursions across U.S. airports, a 15% increase from the previous year. The most serious category, known as Category A incursions (where a collision was narrowly avoided), has seen a particularly sharp uptick, with 23 such events recorded in the first nine months of 2026 alone. O’Hare has accounted for four of those, making it the airport with the highest concentration of serious near-misses in the country.
**Analysis**
The recurrence of these incidents at a single major hub points to systemic issues that go beyond individual controller error. Aviation safety experts have long warned that the U.S. air traffic control system is underfunded and understaffed. The FAA currently employs approximately 10,500 certified controllers, a number that has remained flat for years despite a 20% increase in commercial flights since 2019. At O’Hare, the tower is reportedly operating at 82% of its recommended staffing level, according to a 2025 FAA internal audit. This shortage forces controllers to work mandatory overtime, often exceeding 10-hour shifts, which fatigue researchers say significantly increases the risk of missed communications and procedural errors.
Moreover, the incidents highlight a dangerous gap in ground vehicle management. While aircraft movements are tightly controlled by radar and transponder data, ground service vehicles—tugs, fuel trucks, baggage carts—often rely on radio communication alone. At O’Hare, which sees over 2,000 ground vehicle movements per day, the lack of a fully integrated digital tracking system for non-aircraft traffic has been flagged as a vulnerability. The FAA has been testing a prototype system called Airport Surface Detection Equipment, Model X (ASDE-X) at select airports, but O’Hare has not yet been upgraded to the latest version. This means that controllers must visually confirm vehicle positions through tower windows, a method that becomes unreliable in low visibility or during high-traffic periods.
The economic and reputational stakes are enormous. A single catastrophic collision at a major U.S. airport could result in hundreds of fatalities, billions in liability, and a severe blow to public confidence in air travel. The aviation industry contributes over $1.5 trillion annually to the U.S. economy, and any major disruption would ripple through tourism, cargo, and business travel. The FAA has already announced a review of ground vehicle protocols at O’Hare, and the agency’s administrator is expected to testify before the Senate Commerce Committee next week regarding the broader pattern of near-misses.
