Awwal 20, 1432, April 24, 2011, SPA -- St. Louis' main airport was closed for business Saturday while crews cleaned up after an apparent tornado tore through a terminal, causing several injuries and sending people scurrying for shelter as plated glass shattered around them. Friday evening's storm at Lambert-St. Louis International Airport ripped away a large section of the main terminal's roof, forcing the airport to close indefinitely and diverting incoming flights to other cities.
