Somerset, England

Shortly after midnight on October 30, 1964, a flying machine illuminated with a dazzling red light moved slowly, and at a fairly low altitude, toward James Sharman, a British coal merchant, and three business companions.  The men were on a night fishing trip in Somerset, England.  Like the Exeter UFO, the object spread a red glow over the area, illuminating the bank of a stream and surrounding fields.
 
"There was a herd of about fifty cows in one field,” Sharman reported.  “When the thing stopped overhead, they started making a heck of a noise and chasing around the field.”

The men narrowly escaped being trampled.  “It was . . . pandemonium,” Sharmon said.  “We hid behind a car so the cows wouldn’t sweep us into the water.”  A few minutes later, the unknown craft accelerated and vanished.  The cattle returned to normal only after the UFO had disappeared.

NICAP’s director, commenting on the McDonald and Sharman cases, said people who scoff at unknown flying objects probably would twist the animal-reaction aspect into a new UFO joke.  He added:

“Perhaps now and then a cow may have a startling delusion, though usually cows are rather placid creatures.  But for fifty cows to have terrifying hallucinations all at once would be peculiar to say the least.  Probably they had often seen the moon and Venus as well as cars and planes, without being alarmed.  And even [Donald] Menzel, the most determined UFO-killer would  think twice before saying that the McDonald horse was looking for publicity or the English cows were cultists hypnotized by weird religion.”
