St. Louis Airport Hit by Tornado - Raw Video Footage

Word is that St. Louis Lambert International is going to be closed for a few days.

There were no reports of injuries in the residential areas, despite the wide swath of destruction in a heavily populated area about three-quarters of a mile west of the airport.

Four people were injured by flying glass at the airport when the main terminal was hit by what appeared to be a tornado.

"We're assuming that (a tornado) is what it was," said National Weather Service meteorologist Ben Miller.

Flights from the city's Lambert Airport were being diverted to Kansas City. The airport remained closed indefinitely on Saturday morning, with Monday expected to be the earliest it might open.

Workers and cranes were cleaning debris on Saturday from the roof of one terminal building, where the storm had left gaping holes.

St. Louis Mayor Francis Slay said he was bringing "all hands on deck" to get the airport reopened.
