Taylor Swift’s world tour “The Eras” became the highest-grossing in history, with its income exceeding $1 billion for the first time in the world. As the tour continued this year, Swift was scheduled for three shows in August at the Ernst Happel Stadium in Vienna, Austria. According to rough estimates, about 170,000 fans eagerly awaited seeing and hearing their idol live on stage. However, the Austrian authorities received a warning about a probable terrorist attack, so to avoid a situation like Ariana Grande’s concert in Manchester in 2017, all three concerts were cancelled.
