Several flights at Salt Lake City International Airport (SLC) were canceled Thursday after 11 inbound flights were struck by lightning there on Wednesday.

SLC spokeswoman Barbara Gann tells The Associated Press that 10 arriving Delta flights and one United Airlines flight were struck.

While lightning strikes are not uncommon, 11 strikes in a single day at a single airport is unusual.

Gann tells The Salt Lake Tribune that a few Wednesday evening and Thursday morning flights were cancelled as maintenance crews examined on the struck aircraft.

On March 31, a half-dozen planes arriving to airports in the San Francisco Bay Area were struck by lightning.
