1. Gibraltar International Airport, Gibraltar

Gibraltar Airport is considered to be one of the most dangerous in the world. The reason is simple – there is actually BUSY ROAD leading THROUGH the airport. Gibraltar is very small country located in the south of Spain and the only way to access it is to cross this airport. If there’s a plane landing or taking off from Gibraltar Airport, the soldiers simply close the road and all cars have to wait before the plane lands or takes off. It’s just a miracle there hasn’t been any major accident so far at Gibraltar airport.
