George Weeks posted the link to this the other day, saying:
I love the BBC Archive YouTube channel. So much footage to enjoy. This one is possibly my favourite: The Trans-African Hovercraft Expedition of 1969-70. It's a cross between Biggles, Tintin, Famous Five and Fitzcarraldo.
And he was right.
This film was shot in Francophone Africa, and though I know from a recent rabbit hole that British Africa had all but crumbled by 1962 when Sammy Going South was released, but it's still tempting to place hovercraft beside flying boats and airships as new means of transport that promised to make it possible to maintain the Empire but fell short.
Like Sammy Going South, the film also makes clear the importance of the Muslim faith to Central Africa. And there are thoughtful interludes on slavery and colour that would still be impressive today.
