At approximately 11:15 mountain time, a Cessna 340 struck a bird while on final approach to San Luis Valley Regional Airport. There were no injuries aboard the airplane, but the Sand Hill Crane wasnt so lucky. The pilot said they had just passed over the airport at pattern altitude and were preparing to enter the downwind for runway 20 when a flock of birds came up from below. One bird struck the leading edge of the right wing approximately 3 feet inboard of the tip tank.
