Two experienced pilots lost their lives in a preventable midair helicopter collision after flying dangerously close together in uncontrolled airspace, raising urgent questions about general aviation safety.
Story Snapshot
- Enstrom F-28A and Enstrom 280C helicopters collided near Hammonton Municipal Airport at 11:25 a.m. on December 28, 2025, killing both pilots.
- Michael Greenberg, 71, of Sewell, N.J., and Kenneth L. Kirsch, 65, of Carneys Point, N.J., were regulars at the airport café and departed shortly after breakfast.
- Witnesses saw the helicopters flying low and too close in tandem formation, leading to the crash in a field and backyard with one bursting into flames.
- NTSB investigates; police chief attributes collision to pilots flying too close post-takeoff in towerless airspace.
- No ground casualties thanks to rural location, but incident highlights risks in uncontrolled fields.
Tragic Collision Details
Michael Greenberg piloted his privately owned Enstrom 280C, while Kenneth L. Kirsch flew an Enstrom F-28A registered to a Lancaster, Pennsylvania charter company. The pilots, both local regulars, stopped for breakfast at the Hammonton Municipal Airport café before takeoff. Shortly after departing, witnesses observed the helicopters flying unusually low and close together near Route 30 and Basin Road, about one mile from the airport. The midair collision occurred around 11:25 a.m., sending one aircraft crashing into a field where it ignited, and the second struggling before landing in a resident’s backyard. Greenberg died at the scene; Kirsch succumbed at the hospital.
Uncontrolled Airspace Risks Exposed
Hammonton Municipal Airport (N81) operates without a control tower, relying on visual flight rules and pilots’ see-and-avoid responsibilities. This general aviation facility in Atlantic County supports private and charter flights, where such midair risks heighten without air traffic control. Police Chief Kevin Friel stated reports indicated the pilots flew in tandem shortly after departure, likely causing the collision. Witnesses Diana Cleuff of Shamong and Caitlyn Collins of Hammonton described the helicopters as flying too close, presaging the impact. The rural setting near the crash sites prevented ground injuries, a point Chief Friel called fortunate.
Enstrom F-28A and 280C models are light helicopters suited for private use, with reciprocating and turbine engines respectively. No passengers were aboard either aircraft. The café owner confirmed the pilots’ regular presence, suggesting they may have known each other and chosen to fly together casually. This non-commercial incident underscores formation flying dangers in busy uncontrolled airspace.
Investigation and Official Response
The Federal Aviation Administration confirmed the aircraft models and collision details. The National Transportation Safety Board leads the probe into pilot actions, aircraft condition, and environmental factors. Crash sites remain secured as investigators examine the wreckage. Chief Friel’s early assessment points to tandem flying as the probable cause, aligning with witness accounts of proximity errors. FAA records support the timeline and victim identifications. No preliminary NTSB findings have emerged as of December 29, 2025.
General aviation collisions often result from see-and-avoid failures or improper formations, though no prior incidents at this airport appear in records. Sources show uniform agreement on the tandem flying factor.
Impacts on Community and Aviation
Families of Greenberg and Kirsch grieve amid short-term airport ground closures for inspections. Hammonton residents, including the Collins family whose backyard hosted wreckage, face lasting trauma; Cleuff called the scene horrifying. The local aviation community reflects on safety protocols. Long-term, NTSB may recommend advisories on low-altitude formations at towerless airports, potentially affecting light helicopter operations like Enstrom models nationwide. Minimal economic disruption occurred due to private aircraft involvement. This rare dual-fatality event prompts calls for enhanced pilot vigilance in uncontrolled spaces.
