Who was the first person to successfully navigate the Darien Gap (apart from locals)?

The first overland crossing of the Darien Gap was made by Richard E Bevir (UK) and Terence John Whitfield (Australia) in their Land Rover 'La Cucaracha' during the Trans Darien Expedition. The gap, which consists of dense jungle and obstacles such as numerous rivers, is famous for being the 'missing' portion of the pan-American highway that links North and South America. They departed from Chepo, Panama, on 3 February and reached Quibdo, Colombia, on 17 June 1960. They averaged 201 m (220 yd) per hour.
