today and everything was routine. They were landing from the south using Runway 36 for take-offs as well. Then something odd happened. An ATA 737 taxied from Terminal A all the way down to the other end of the field and took off on Runway 18. At first I thought they were changing the active to 18, but he was the only one to do it. That plane took off on 18 with a line up of planes waiting to both land and take-off on 36. After he left, operations continued on 36. Why did the ATA plane use 18????
It does happen... if there is a MEL that reduces the field performance of the plane or if its just quite heavy, they'll do that so that it won't encroach on the restricted airspace if it has an engine out situation.
