While combating a computer networking problem, scientists and engineers at Peterson Air Force Base, Colorado had to figure out how to rewire their units to communicate at the base's new Y2K missile warning center. The problem was, the conduits were 40 feet long, already filled with wires and only large enough for mice, not men.
Enter Misty, a ferret and a family member of the family of Lt. Col. Randy Blaisdell for six years. Randy remembered from history that ferrets were used to pull wires through tight spaces in World War II-era airplanes. Blaisdell tied one end of a piece of yarn to Misty's midsection. The other yarn end was tied to a piece of wiring. Misty crawled through the pipes and let her natural curiosity take its course. One hour and several trips later, Misty was finished, the computers networked and the small furry ferret was rewarded with her favorite treat: strawberry Pop Tarts. source
