Analysis

Two ag aircraft were spraying the same field. According to several witnesses, 1671S was heading south and 3660X was heading east. Both aircraft were actively engaged in the spraying operation but did not seem to the witnesses to be coordinating with each other. 3660X had started a left turn to a northerly direction when 1671S pulled up and collided with 3660X. Both aircraft impacted the terrain immediately after the collision.
