Sixty years ago a football match ground to a halt when unidentified flying objects were spotted above a stadium in Florence. Did aliens come to earth? If not, what were they? It was 27 October 1954, a typically crisp autumn day in Tuscany. The mighty Fiorentina club was playing against its local rival Pistoiese. Ten-thousand fans were watching in the concrete bowl of the Stadio Artemi Franchi. But just after half-time the stadium fell eerily silent - then a roar went up from the crowd. The spectators were no longer watching the match, but were looking up at the sky, fingers pointing. The players stopped playing, the ball rolled to a stand-still. One of the footballers on the pitch was Ardico Magnini - he was something of a legend at the club and had played for Italy at the 1954 World Cup. "I remember everything from A to Z," he says. "It was something that looked like an egg that was moving slowly, slowly, slowly. Everyone was looking up and also there was some glitter coming down from the sky, silver glitter. "We were astonished we had never seen anything like it before. We were absolutely shocked." Play was suspended because spectators saw something in the sky, according to the referee's match report. Among the crowd was Gigi Boni, a lifelong Fiorentina fan. "I remember clearly seeing this incredible sight," he says. His description of multiple objects differs slightly from Magnini's. "They were moving very fast and then they just stopped. It all lasted a couple of minutes. I would like to describe them as being like Cuban cigars. They just reminded me of Cuban cigars, in the way they looked." La Nazione's headline reads: Glass fibres fall on Tuscan cities after globes and flying saucers pass by. Lower headline: The sighting over Florence (with a photograph, now lost, of the UFO). Boni has spent many years reliving that day in his mind. "I think they were extra-terrestrial. That's what I believe, and there's no other explanation I can give myself." More via BBC News.
