At Takoradi Airport, Ghana there is a main road crossing the runway between the town and the local residentual area. Anything and everything crosses the runway there. People, cars, trucks you name it un checked by any form of security. However to their credit, they have a siren and booms to stop people and traffic when an plane is about to land. This is also their local airfarce (spelling intended) base.
Really?
Been here over 5 years and never noticed it! Maybe time to get my eyes checked.
Or are you referring to the small dirt track the locals use to scurry across the runway illegally?
