A heavy sea fog and one of the largest ships in the U.S. Navy brought America’s Cup racing off San Diego to a grinding halt.

In one of the strangest postponements of the 144-year history of America’s Cup competition, organizers stopped the countdown to the start of a race on the challenger course when the 94,000-ton, USS Abraham Lincoln made a surprise entry from a heavy sea fog onto the race course.

The Abraham Lincoln was looking for a clearing in the fog to airlift passengers to San Diego.
