There are several claims that twisters have lifted cows into the air:
Several cows and one bull survived being carried more than a quarter mile by a tornado Tuesday evening near Elgin. The cattle were reportedly tossed over fences into an adjacent pasture.
From a physics perspective sky-bound cows seem unlikely. The houses and cars that tornadoes play with are very heavy but also hollow and low density. Solid objects are much harder to move. A human terminal velocity is about 120 mph in a belly-down position (maximizing drag) but humans can fall at a speed of up to 310 mph in a streamlined vertical dive. This is faster than the most powerful tornado on record. A cow, which can weigh over a tonne, presumably could fall at a velocity of well above 200mph. Terrified cows may find themselves in odd places, and debris are still highly lethal. But flight?
The poorly-resolved "cow" in the first film could be a piece of siding or other debris. Instead of "being carried over a fence" terrified bovines simply jumped and/or trampled the damaged(?) fence. The article provides no evidence besides "someone said so".
Has there been a well-documented "flying cow"?
