What Cause’s flight delays?
What does the Air traffic controller do?
How many airplanes are used in the U.S.?
We think that in order for the airports not to have flight delays; we need to get more airplanes or have more airplanes with more room. So in order to not have as many airplanes in the air at one time; there needs to be at least one day out of the week they do not fly planes.
