Vintage Videos Of Travelling From Capetown To Cairo In 1959

This is a great collection of videos about the Wally Byam Caracan Club International travelling from Capetown to Cairo in 1959. Imagine a group of trucks towing Airstream trailers through the middle of Africa in 1959? 36 vehicles and over 100 people! There is a lot of really neat moments throughout the videos, such as the encounters with the Pigmy people that had never seen a balloon before. Does anyone have more information about this expedition?
