At approximately 1144 central time, a Cessna 172S crashed after reporting a bird strike. The flight instructor and student pilot were killed. Radio transmissions showed the pilot reported the airplane was going down. The pilot said, Send somebody to pick us up. I think were going to be fine. We hit a bird, but we gotta go down. We cant keep it straight with the power on. The pilot then advised he was going to end radio contact. The wreckage was contained within a path 60 feet long and the wings displayed leading edge damage. The flaps were extended 20 degrees. Evidence of a bird strike was found about 12 inches outboard of the left wing landing/taxi light.
