Recently seeing Pinochet - Free Helicopter Ride t-shirts was a bit of an unknown for me. My first knowledge of Free Rides comes from the Dirty War - Guerra Sucia of 1974-1983 in Argentina. The phrase Flying Nuns was used denote the execution of an unknown number of Catholic nuns by tossing them from a helo.
The Dirty War was basically government action against socialists. Different sources claim different numbers but during The Dirty War, The Disappeared Los Desaparecidos, Argentine citizens abducted by military or government police, may number as high as 30,000. Of that number an estimated 1,500-2,000 were tossed out of aircraft into rivers or the Atlantic Ocean. Some victims were already dead but others were in a drugged state.
Much of the confinement-interrogations-executions occurred at the former Navy School of Mechanics in Buenos Aires. Its infamy is on par with that of Prinz-Albrechtstrasse in Berlin or Lubyanka Prison in Moscow.
Some speculation that citizen pressure on the Argentine government due to their Dirty War resulted in the Falklands Malvinas War of 1982. Government tried to unite citizens with a war and losing both conflicts, got both sides of their ass kicked.
Yes, the Argies were guilty of about six times as many “desaperdecedos” (?) as always-getting-the-blame Chile.
