Overview
- Surveillance footage reviewed by the NTSB shows two Enstrom helicopters flying closely in a slightly staggered pattern before converging and making contact near Hammonton, N.J.
- The collision at about 11:24 a.m. in late December killed pilots Kenneth L. Kirsch, 65, and Michael Greenberg, 71, after a morning that began with departures from Vineland-Downstown at 9:48 a.m. and an arrival at Hammonton at 9:58 a.m.
- Video indicates one helicopter entered a tumbling descent as the other briefly pitched up, then yawed clockwise and descended rapidly out of view.
- The crash site lay about 1.5 miles southwest of Hammonton Municipal Airport with a debris path of roughly 1,211 feet, and paint transfer suggests the 280C’s tail rotor contacted the F-28A’s main rotor.
- Investigators report no preliminary ADS‑B data for the accident leg; wreckage was recovered for further examination, weather was 10-mile visibility with light winds and a 1,400-foot overcast, and no probable cause has been determined.
