WHEN we filmed United 93, we had a bible to guide us every step of the way.

It was 567 pages long and beautifully written. It summarised with exceptional clarity 1,200 interviews conducted in 10 countries, more than 2.5 million pages of official documentation and 19 days of public hearings.

It was called the 9/11 Commission Report. Without it, we could never have reconstructed what happened aboard the hijacked passenger jets, nor even begun to understand the complex forces that led up to the attacks on September 11th 2001.

The 9/11 Commission report cost £8.1mil-lion. Astonishingly, for a government publication, it became a bestseller on its release.

It stands today as a powerful and impressive exercise in accountability from a society mature enough to know that when faced with a calamity on the scale of 9/11, government's first task is to find out what happened and why.
