Meanwhile, in other high-altitude cow transportation news:  

A plane was forced to make an emergency landing because the almost 400 cows it was transporting were giving off too much heat. The Boeing 747 was forced to touch down at Heathrow Airport in London. The plane was flying over the Irish Sea when a fire alarm sounded from where the 390 cows were being kept, reports the Sunday People. After the plane landed, technicians inspected the plane, but found no evidence of any smoke. Instead, they concluded that the alarm was set off by the cows.

If they learn how to make fire, we’re buggered. Mercifully, there are no reports of a catastrophic methane build-up.
