Détails:
The Skyvan collided in midair with a Cessna 207 (N800GA), shortly after taking off from runway 36. Both aircraft crashed.
A witness observed the Skyvan descending toward the ground in a counter-clockwise spiral from about 800 feet above the ground. The wreckage of Cessna, entangled with the wreckage of N451SA, was found on the surface of a frozen lake. The weather conditions that prevailed at the time of the accident included clear skies; visibility, about 60 miles; wind, 045 degrees at 15 knots.
PROBABLE CAUSE: "Inadequate visual look-out by the pilots of both airplanes, which resulted in their failure to see-and-avoid each other's airplanes."
