Two aircraft ran off the runway on consecutive days in mid-August 2026 at Spirit of St. Louis Airport in Chesterfield, Missouri, a busy general-aviation and corporate field on the western edge of the St. Louis metropolitan area. In both cases the aircraft left the paved surface and came to rest off the runway, and in both cases everyone aboard walked away without reported injuries.
The back-to-back incidents drew attention precisely because they ended so undramatically. Runway excursions are among the most common categories of aircraft accident, yet they rarely produce fatalities when they happen at low speed on landing or during a rejected takeoff. The St. Louis episodes fit that pattern, and they offer a window into why an event that sounds alarming can leave passengers and crew unharmed.
What happened at Spirit of St. Louis Airport
The most recent excursion occurred just before 3 p.m. on Thursday, August 14, 2026, when emergency crews were called to the airport for an aircraft that had gone off the runway. Early reports indicated there were 10 people aboard and no injuries. Roughly 24 hours earlier, on August 13, another aircraft had also left the runway at the same airport, again without injuries, according to local reporting on the two incidents. Photographs from the scene showed one aircraft resting in the grass alongside the pavement.
The two events happened at different points on the airfield, and investigators believe a collapse of the landing gear may have played a role in at least one of them. Because Spirit of St. Louis Airport handles corporate jets, charter flights, flight training and private aircraft rather than scheduled airline service, the planes involved were consistent with the business and general-aviation traffic that dominates the field.
Why a runway excursion is survivable
A runway excursion is any event in which an aircraft veers off the side of the runway or rolls off the end. Unlike a mid-air breakup or a high-altitude loss of control, an excursion usually unfolds at relatively low speed and close to the ground, where the airframe’s crash protection and the occupants’ seatbelts do their intended job. Modern aircraft are engineered to absorb the energy of such an event, and airports maintain graded safety areas beyond the pavement to slow a departing aircraft before it strikes an obstacle.
The outcome nonetheless depends heavily on speed, terrain and what the aircraft encounters after leaving the runway. Excursions that end in soft grass, as at least one of the St. Louis events did, tend to be far less severe than those in which an aircraft strikes a ditch, embankment, fence or body of water.
Landing gear as a suspected factor
Investigators’ early focus on the landing gear points to one of the recurring vulnerabilities in general-aviation operations. A gear that collapses on touchdown, or that fails to lock fully into place, can send an aircraft skidding off its intended path even when the approach and landing were otherwise normal. Mechanical failure, improper configuration and hard landings are all potential contributors, and separating them is a central task for accident investigators.
Determining a definitive cause takes time. The record of general-aviation accidents compiled by safety databases shows that gear-related excursions are a persistent theme across corporate and private flying, which is one reason regulators emphasize pre-landing checklists and recurrent pilot training.
How these events are investigated
In the United States, the Federal Aviation Administration and the National Transportation Safety Board share responsibility for examining aircraft accidents. The FAA looks at regulatory compliance and airworthiness, while the NTSB works to establish the probable cause and to issue safety recommendations that can shape future rules and procedures. Investigators typically examine the aircraft’s maintenance history, the crew’s actions, weather conditions and any available flight and voice data.
For excursions with no injuries, the process is less urgent than for a fatal crash but no less methodical, because minor events often reveal the same underlying problems that produce catastrophic ones. Two similar incidents at a single airport within a day of each other are the kind of coincidence investigators will scrutinize to determine whether a common factor, such as runway conditions or a shared aircraft type, was at work.
The wider picture at a corporate airport
Spirit of St. Louis Airport is one of the busiest general-aviation airports in Missouri, serving a steady stream of business travelers, cargo operators and training flights. High traffic volumes at such fields mean that isolated incidents are, statistically, to be expected over time, even as the overall accident rate for professionally flown corporate aircraft remains low.
The reassuring takeaway from the August 2026 excursions is that the layered defenses built into aviation, from aircraft design and airport safety areas to emergency response, functioned as intended. Everyone aboard both flights survived, and the aircraft, rather than the occupants, absorbed the consequences of leaving the runway.
