Lightning strikes airport passenger in Columbia. COLUMBIA, SC -- Lightning struck a passenger who was getting off a plane Saturday at the Columbia Metropolitan Airport, where a flight had been diverted because of bad weather. The woman, whose name was not available Sunday morning, was hospitalized in the Columbia area and in stable condition Saturday night, an airport spokeswoman said.

Although most lightning will strike within 10 miles of its parent thunderstorm, it can strike much farther away.
