For the first time in U.S. history, no commercial aircraft are flying anywhere. The Federal Aviation Administration has grounded the nation's airlines after four hijacked planes crashed. The F-A-A says no planes will be allowed to fly until tomorrow (Wednesday) at 11 A.M. Minnesota time at the earliest. As Minnesota Public Radio's Elizabeth Stawicki reports, passengers arriving in the Twin Cities knew nothing of the New York and Washington attacks until they joined crowds of people gathered around airport television monitors.
