9/11 could have happened 25 years ago, few days after Christmas 1985. At 9am of 27th December '85, a four men commando breaks in "Leonardo da Vinci" Airport in Rome and opens fire on passengers at check-in. Same morning, same hour: at Schwechat Airport in Vienna a terrorist commando shoots grenades against El Al counters. Two planes hijacked simultaneously. Hundreds of hostages.
