Alouette 111B. Taken during the flypast over Salisbury on the 28th November 1972.

Note the tropical air filter over the engine intake, one either side. Dust/sand is a major problem with all engines in Africa, air filters have to be large and efficient. Roundels just under the engine, the registration just forward of the rear undercarriage leg below the sliding door runner, painted in black, always hard to make out, the last two numbers of the serial also appeared on the front of the helicopter fuselage in front of the pilot. The Alouette 111B was the most common type used by the Rhodesian Air Force, it struggled a bit when operating during the hot weather at the high altitudes, Salisbury itself, part of the 'Highveld' is 5000 feet above sea level, the Zambezi Valley around 2000 feet but very hot.
