10. Congonhas Airport, Brazil. The most dangerous and most unusual at this airport is the fact that it is located only 8 km from the city center. For security reasons, the densely populated and large cities in the world are building their airports on the outskirts or even a few kilometers from the city’s borders, but apparently the residents of São Paulo have not heard about this. Each landing of the aircraft at this airport becomes a real test not only for the passengers of the plane, but also for the residents of the city.
