I will post the story of my dad’s cow strike, on roll out with a C-310, after the comments below.
You will notice the plane doesn’t land straight. Maybe the pilot intentionally curved to the left on rollout, maybe not. You probably noticed the heavy application of rt rudder after impact and during the landing. The cow may have made a last second effort to escape, and may have only had 2 feet on the ground at the moment of impact.
Upon review, I noticed the pilot was looking to the right most of the time, and he was obviously showing off to his passenger without checking the pasture out in advance of making a low pass.
I worked on a wing replacement job back in the summer of 88. An Air Tractor agplane had struck, and broke the top 3 feet off of a powerline brace pole. The pilot was nearly empty of spray, yet he dumped the remainder, and flew under full power, nealy full lt aileron the 12 miles back to the airstrip. It was a hand full after landing as the rt main gear was bent. He went in the office and told his boss: “You better go look at your plane, meanwhile I’m lying down on the couch for a while”.
Further review:
I see the full rt rudder was only for a momment after impact and touch down. The hip bone structure is clear on what appears to be a holstein dairy cow, indicating her direction of travel, right as she appears from under the wing. She would appear to have been running in the same direction of travel as the plane. The impact/push was enough to send her tumbling.
