This morning, as I was walking from my dorm to the Cafeteria on campus at St. Cloud State University, I heard at first the sound of a very loud jet and then I looked to the east, which is in the direction of the airport, I didn't see anything at first. I kept looking and then I saw a 737-800 fly really low over the college as it was turning towards the southwest and climbing. It had Winglets on it and it was painted mostly white, except for some paint here and there on it. Man did it look quite low as it was climbing. This was at about 7:30 am this morning. My big question is, why was there a 737-800 departing from KSTC, as there is no scheduled 737 services into St. Cloud. Also, the runways at St. Cloud are a bit short to allow for long-distance flights. I thought maybe it was a BBJ or something....
