A midair collision at a small Pennsylvania airport killed the pilot of a light plane and injured two state troopers when the aircraft struck a police helicopter that was hovering beside the runway during a training exercise. The crash happened the evening of August 19, 2026, at Carlisle Regional Airport in Cumberland County, when a Cessna 150 collided with a Pennsylvania State Police Bell 407 helicopter.
Federal investigators say the small plane appeared to be out of control in the moments before impact, and they have recovered onboard data that could help explain how a routine landing ended in a fatal accident. The pilot was later identified as a physician and certified flight instructor, deepening the shock of a crash that unfolded during what should have been an ordinary evening approach.
What happened at Carlisle Regional Airport
The collision occurred shortly before 7 p.m. as the Cessna 150 was attempting to land. The Pennsylvania State Police helicopter was hovering over a grassy area beside the runway as part of a training exercise when the fixed-wing plane came off the runway and collided with the rear of the aircraft. Two troopers aboard the helicopter were injured, while the pilot of the plane was killed. According to a briefing described by NBC10 Philadelphia, National Transportation Safety Board investigators recovered data cards from the wreckage that may provide new detail about the sequence of events, and the aircraft debris was relocated to Delaware for closer examination.
The pilot who was killed
The Cumberland County Coroner’s Office identified the pilot as Dr. Paul Sokoloski, 57, of Hershey, Pennsylvania. He was a physician with Penn State Health and also held certification as a flight instructor, meaning he was an experienced aviator qualified to teach others to fly. The two Pennsylvania State Police troopers hurt in the collision were treated for their injuries. The involvement of a state police helicopter gave the crash added weight in the region, both because law enforcement personnel were among the injured and because the aircraft was engaged in official training when it was struck.
The maneuver investigators described
Early accounts from the NTSB sketched an unusual and abrupt sequence in the plane’s final seconds. Investigators said that as the Cessna came off the runway, it suddenly increased its pitch in a severe nose-up maneuver, then turned and leveled off before flying into the back of the hovering helicopter. That description, relayed by CNN, suggests the aircraft was not on a stable, controlled path when it made contact. Whether the sharp pitch-up reflected a mechanical problem, a loss of control, or some other factor is precisely the kind of question the recovered data and the physical evidence are meant to resolve. Investigators have emphasized that the cause remains undetermined pending a full analysis.
Why hovering aircraft complicate a busy airfield
The collision highlights the particular risks that arise when different kinds of aircraft share the same small patch of airspace. Helicopters can hover in place, while fixed-wing planes must keep moving forward to stay aloft, and the two operate under different flight profiles even at a modest general-aviation field. A helicopter conducting a training exercise beside an active runway occupies airspace that a landing airplane may pass close to, and coordination between the aircraft and any controllers or ground personnel becomes essential to keeping them safely separated. Small airports like Carlisle often do not have the staffed control towers found at larger commercial fields, placing more responsibility on pilots to see and avoid one another and to communicate their intentions clearly over shared radio frequencies.
How the NTSB will build its case
As with all civil aviation accidents, the NTSB is leading the investigation and will work to establish a probable cause. Investigators will study the recovered data cards, examine the wreckage that was moved to Delaware, review any available video and witness accounts, and reconstruct the flight paths of both aircraft in the seconds before the collision. They will also look at the plane’s maintenance records, the pilot’s experience and medical history, the training exercise the helicopter was conducting, and the communications between the aircraft. The agency typically issues a preliminary report within a few weeks that lays out the known facts without assigning blame, followed much later by a final report that identifies the cause and may recommend safety changes.
A community waiting on the findings
The Carlisle crash left a physician and flight instructor dead, two state troopers injured, and a community grappling with how a training flight and a landing attempt could intersect so catastrophically. The confirmed elements are clear enough: a Cessna 150 on approach, a state police Bell 407 hovering beside the runway, an abrupt nose-up maneuver, and a collision with the helicopter’s tail. What remains open is the why, and answering it will fall to investigators sifting through data cards and wreckage over the months ahead. Until the NTSB completes its review, the accident stands as a sober example of how quickly a moment of shared airspace at a quiet regional airport can turn deadly.
