Is an ostrich the fastest animal in the world?

Ostriches might be tied with North American Pronghorns as being the 2nd fastest land animal. The consensus of a variety of sources I have read indicate Cheetahs are the fastest for a short distance. They are frequently being quoted as being capable of going 70 mph, but only for a short distance. Over longer distances, I have seen both Ostriches and Pronghorns quoted as being able to go 60 mph.
