Good morning. It is a sombre day for the nation as people gather to mourn and remember the nearly 3,000 victims of the attacks on September 11 2001, when 19 al-Qaida hijackers seized control of four airliners, slamming two of the planes into the World Trade Center, one into the Pentagon in Arlington, Virginia, and the fourth into a field in western Pennsylvania.
We have comprehensive coverage of the anniversary, which will be marked by ceremonies around the world. There are stories of the day from people who were there. Stanley Praimnath and Brian Clark were two of only four individuals known to have survived above the impact zone in the south tower, and they spoke to our Washington bureau chief David Smith. Anna Sweeney Rossman was five when her mother, Amy Sweeney, a flight attendant, was killed onboard American Airlines flight 11, and she spoke to Ramon Antonio Vargas about how the events of that day have cast a shadow on her life.
CIA veterans spoke to Robert Tait about the chaos and confusion in the agency as the unprecedented attacks unfolded, and Guardian readers have told us about how September 11 changed their lives. Jason Burke, our international security correspondent, writes that while al-Qaida leader Osama bin Laden may have shaken the world on 9/11, it is clear today his wider plans failed.
But we also have to acknowledge that the world’s most powerful country responded to the worst terrorist attack in its history by inflicting terror of its own – around the world, and at home. This read from David Smith outlines how the day saw heroes emerge showing the best of America, and then the response of US governments left a dark legacy – Guantánamo Bay, the Abu Ghraib scandal – which continues to unfold to this day.
Those who remember September 11 will never forget the haunting images of that day, including the missing people posters that were put up in the confusing aftermath of the collapse of the towers in New York. Captured by the photographer Phil Buehler, they will form part of a new exhibition, and some can be viewed here. As we look back on a day that reshaped our world, our thoughts remain with the victims, their families, and all those whose lives were irrevocably changed 25 years ago.
