A family friend of mine, now retired, hit a herd of cows in the flare at night while landing in Nagpur, India. The incident happened about 20-odd years ago. A/c was an Indian airlines B737-200. Almost touched down, or had just touched down, can't remember now, when he saw around 5 cows running across. The port wing hit the cow(s)and all leading edge slats and the wing were damaged. Upon leaving the runway, a/c had lost all hydraulic fluids and there was no steering, braking, etc. He then cut both engines and was coasting without directional control, until the a/c slowed down and finally came to a halt, with the nosewheel hitting the ledge of an underground tank. It was a water sump, and he said that he had fired both engines out and was scared that the nose might fall into the tank, probably causing havoc or fire with the avionics bay if it went in. But by sheer luck, he mentioned, the nose wheel hit the ledge at one of the 4 corners, and so they were very fortunate, the a/c did not nose into the tank.
Quite a story.
