A Portuguese cargo ship struck an oil tanker that was carrying fuel for the U.S. military off the English coast on Monday, sparking explosions, a frantic rescue mission and concerns of a possible oil spill. Owners of the cargo ship say one of its crew members is missing. NBC's Kelly Cobiella reports for TODAY.
Concerns grew over the environmental impact from the fiery collision between a fuel tanker and a cargo vessel off the British coast in the North Sea a day earlier.
