I want to know the answer to the following question:
What is an airport?
All the background I'm provided with is that "An airport consists of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off or a helipad, and often includes adjacent utility buildings such as control towers, hangars  and terminals.". Is that enough to answer the question?
Answer: no
