Soaring to 646 meters or 2,120 feet, the Warsaw Radio Mast was built to broadcast radio programs to Polish-speaking audiences across Europe.

  • Role: subject
  • In the article: The piece opens with the mast: built in 1974, the tallest structure on Earth, it broadcast Polish-language radio across Europe. By 1991 its guy wires needed replacing; on 8 August 1991 a main cable was released before the temporary ones were in place, the wind twisted the tower and it fell, injuring no one.
  • Why it matters: The collapse is the hook for the explainer on how guyed towers and their pinned bases work; the rest of the piece is generic engineering.
