Editor´s letter

Ten years on from 9/11 and another wave of change is about to sweep over the defence and security industries. Every generation has its ´where were you when...?´ moment. These moments are often the start of a chain of events so important that the world is tangibly different from then on. For one generation it was the assassination of President Kennedy on 22 November 1963. For another it was the attacks of 11 September 2001 on New York´s World Trade Center, the Pentagon in Virginia and an unreached target in Washington DC.
