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.
(I ask everyone who believes that the United States has God on its side to consider the theological implications of lightning striking the Mall on the 4th of July.) The NOAA website says that 400 people a year get struck by lightning, but doesn't make it clear whether that's worldwide or nationwide. Between 1997 and 2006, 437 people in the United States died from lightning strikes. Wyoming is the most dangerous state for lightning, and no one died of lightning strikes in Alaska, Delaware, D.C., Hawaii, New Hampshire or Washington state.
