Take a moment to click on and view the video below. You will

thousands of individual moving dots, each one representing an
individual airplane identified by air traffic control radar. You
will also see that as the earth rotates, certain areas are in
daylight while others are in nighttime. During daylight the air
traffic increases exponentially, and though Europe has high air
traffic density during its daylight hours, no other place on
Earth has more air traffic than over the daytime USA. Now
consider this: The video is of a single 24 hour period on Earth.
Tens of thousand of flights are clearly visible, and yet not one
of them crashed into another. Not one! How can that possibly be

answer is air traffic controllers, whose jobs it is to guide
these airplanes safely and efficiently through the available
airspace. Air traffic controllers do this day in and day out,
