Williamson Diamond Mines

Has Operated from 1940 to Present

Country of Origin – Tanzania

Founder/Director – Dr. John Williamson

As one of Tanzania’s largest and most productive diamond mines, a certain number of aircraft were needed to move workers, staff and equipment around the country and sometimes even further afield. The company itself possessed a small number of C-47s, although it was its sole DC-4 that continued to retain its long historical attachment to SEN. Having been passed over for conversion to a Carvair thanks primarily to its DC-4 rather than the preferred C-54 construction, former BUA stalwart G-AOXK would eventually find herself being handed over to Aviation Traders and in July 1963 she departed Southend for African climes as 5H-AAH. Needless to say, over the next few years this DC-4 would continue to return to SEN for regular checks, overhauls and maintenance with her last recorded visit taking place on September 15th 1967.
