Horses transformed transportation, agriculture and warfare thousands of years ago, while the B 2 Spirit represents modern stealth aviation. The comparison compresses an enormous history of human innovation into one frame, but the timeline is misleading. Modern domestic horses spread widely about 4,200 years ago, while the B 2 first flew in 1989.
