1. ICE BREAKER
Nome, Alaska USA
√ Two 2 1/2 pound GPS-guided UAVs that tolerate extreme cold helped bring fuel to snowbound Nome, Alaska over two weeks in January. On daily photographic missions, the Aeryon Scouts helped University of Fairbanks researchers map ice thickness in the frozen harbor so a Coast Guard icebreaker could slowly guide a Russian fuel tanker close enough to pump the fuel to shore.
