The Observation Tower at Burlington International Airport was once an Air Traffic Control Tower but now it is a place where anyone can come to get a nice view of the tarmac, runways, and planes to name a few. You will also get to hear the live communication between the Control Tower and various aircraft pilots via speakers in the Observation Tower. To get to the tower, head on up to the 2nd level of the airport and walk towards the check-in gates. There are signs clearly marking the location. This is a great place to visit for aviation fanatics like me. When no one is around, I get to play air traffic controller. :-)
