( CNN ) -- The main airport in St. Louis is expected to operate a full flight schedule Tuesday , less than four days after a powerful tornado tore through the facility , airport officials said . But restoration efforts are far from over at Lambert-St. Louis International Airport , where the Friday night storm shattered windows and ripped off part of a roof . `` It obviously just took a couple of minutes for the damage to occur , '' Airport Director Rhonda Hamm-Niebruegge told CNN 's `` American Morning . '' `` It will take weeks , maybe a couple of months , to clean up all of it . '' Still , Hamm-Niebruegge said efforts to get the facility up and running again have been `` miraculous . '' American Airlines returned to service on Monday , officials said . The last of the airport 's 13 airlines -- Cape Air -- will resume flights on Tuesday , airport officials said . American and Cape Air were among the hardest hit after the storm , which devastated the airport 's C concourse . The tornado damaged 750 homes near the airport , Missouri Gov . Jay Nixon said . And preliminary National Weather Service estimates released Saturday show the tornado packed winds between 111 and 165 miles per hour when it hit the airport . There were no fatalities reported -- a fact that Nixon characterized as `` absolutely amazing . '' Tornado cripples St. Louis airport . At the airport , Hamm-Niebruegge said the facility 's design -- and the way people responded to warnings -- played a key role . `` It is a historic building , and it 's built very , very well . I think that had a part to do with it , but we also had very early warnings , '' she said . Besides damage to homes and the airport , the strong winds also hit businesses and tore through the roof of a Ferguson , Missouri , church where dozens had gathered on Good Friday to watch the movie `` The Passion of the Christ .
