On this day, 20 December 1973, Spanish fascist prime minister who was hand-picked as general Francisco Franco's successor, Luis Carrero Blanco, was assassinated in Madrid. Basque separatists ETA had spent five months digging a tunnel under a road he went down to attend mass. They detonated his car 20 metres into the air and over a five-storey building, earning Blanco the nickname of "Spain's first astronaut".
