Dateline: Kruger National Park South Africa. While watching a herd of impalas on the side of the road, a group of tourists (and the Impalas) gets surprised by an unexpected cheetah attack. As the world's fastest mammal attempts to corner it's prey, one Impala has other ideas - namely a head first power jump thru the open window of a nearby SUV. For a split second the pursuit takes a possibly deadly turn as the cheetah contemplates continuing the chase, but turns its attention towards another, more accessible, lunch. Once the cheetahs had left, the tourists merely opened the car door and let the quick thinking impala out.
