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.
All the time! Okay, not all the time, but itâs definitely more likely than dying in a plane crash. In fact, itâs estimated that lightning strikes every airplane at least once per year. (The odds of being personally struck by lightning is about 1 in 3,000 in a personâs lifetime.)
