Incident Overview and Aircraft Involved A Cessna 182, registration N6384A, and a Piper PA-28, registration N4676R, were involved in a midair collision. The Cessna 182 had four skydivers aboard, while the Piper PA-28 carried a student pilot and a certified flight instructor. ## Sequence of Events Two Cessna 182 aircraft took off in formation from runway 10. After takeoff, the pilot of N6384A discontinued formation flight and departed to the southeast, while the other Cessna departed to the northeast. At approximately the same time, the Piper PA-28, N4676R, was approaching the airport. ## Collision and Investigation Findings The two aircraft subsequently converged and collided about 1-1/2 miles southeast of the airport. No known witness observed the collision, and the altitude and headings of the aircraft were not verified.
