'The Short Bristol Seaplane being launched at Rochester today for tests. A flight over the 'Mountains of the Moon' to Lake Kivu, 5000 ft above sea level in the Belgian Congo, Central Africa, is to be undertaken shortly by Sir Alan Cobham and five other men.' The Bristol Jupiter-powered Short S.11 Valetta first flew in 1930 as a research aircraft. Cobham landed back at Rochester in September 1931, having flown 12,300 miles.
