 The term originated at the Uganda–Kenya border crossing at Busia, where a kilometre separates the downtown area from the border post on the Ugandan side.Travellers dropped off at the bus/taxi station by buses or taxis, or those coming to Uganda from the Kenya side, were ferried over this distance by enterprising cyclists, who would attract business by calling "border, border".The title "Captain" is applied to all pilots, not just those in command of a plane.
