The Tarot card number 16 is the Blasted Tower. The card shows a tower which is hit by lightning bolt (rayo) and flames of fire. Two people are falling head-first (de cabeza) to the hard rocks below and one can only fear what will happen to these poor people when they "hit rock-bottom" (= reach the ground). The full name of this card is "The Lightning-Struck Tower", and that adds an electrifying element of sudden "shock" to the scene. The people inside the tower couldn't see this coming, and then suddenly their whole world was turned upside-down.
The tower card symbolises destruction. It may be a reference to the biblical story of the Tower of Babel, where God destroys a tower built by mankind to reach Heaven. It might then symbolise God's punishment for pride.
Some people, like Ian R. Crane, believe in the conspiracy theory and relate the tower tarot card to the attacks on the Twin Towers on the 11th of September, 2001. The fact that the flames go sideways, instead of upward, the falling/jumping people, the rubble (escombros) in front of the tower and the meaning of the card (negative change), make people like him believe, as he said in a presentation, that "the world drew (extrajo) the tower tarot card on 9/11".
