South Africa's racist white government promoted its tourist industry overseas while, at home, striking employees of the South African Transport System, SATS, were routinely shot.

Occasionally, in London, the official Anti-Apartheid Movement (AAM) would respond to this barbarism by convening a genteel vigil of protest outside the main London office of South African Airways (SAA) at Oxford Circus, in the heart of London's West End.

Despite being expelled from the AAM, City of London Anti-Apartheid Group (City Group) used to force the SAA office to close down for whole days. We would make their business impossible to transact when everybody in the store who had appeared as a potential customer suddenly transformed into an activist. Anybody looking in through the enormous plate-glass windows would witness a full-scale anti-apartheid demonstration taking place within.

When SAA's security staff began to recognize City Group leaders, we resorted to ludicrous disguises. Here's the Rev. Michael Burgess addressing the faithful in front of the South African Embassy after causing SAA to lose another business day during 1987.
