Yes, the pavement length is only 6365' . . . but it has been in service for many decades, wet and dry, for thousands of successful landings. The incident/accident rate for the amount of traffic is not extraordinary. Before the life of A320s, Trans-Brasil B727s had also operated at this airport. Remember?
How many people have said, "but we've always done it that way", as they gazed over the smoking hole. Just because they got away with it doesn't make it right or smart.
