Six films of early exploration
Introduced from the Royal Geographical Society by the pioneer polar explorer Duncan Carse

'Congratulations Cobham! Magnificent show: now sit down and tell me all about it.' - the words of King George V to the pioneer aviator Sir Alan Cobham, on his return from his great trail-blazing flight from Croydon to Cape Town and back.

Cobham had taken off from Croydon aerodrome in a primitive single-engined De Havilland biplane on a grey November morning in 1925. Ahead stretched a journey of some 8,000 miles - all dependent on that single engine: a flight which was to include the first aerial photography of the pyramids; getting lost in a sand-storm; landing among tribes who had never seen an aeroplane before - and nearly crashing into the Victoria Falls when spray swamped the engine.

At the end of it all, a triumphal welcome in Cape Town, a unique picture of an Africa now long since vanished: and the royal command to 'tell me all about it'.
