As 11 September approaches, American businessman Charles Wolf is a man in demand.
Katherine Wolf had started a new job on the 97th floor
As well as fending off business calls to his New York office, the 52-year-old is receiving a stream of calls from media organisations, keen to get the widower's viewpoint five years on from the disaster which transformed his world.
Mr Wolf says he "rolls with the punches", as the media attention flows, accepting that the marking of that terrible day is inevitable.
.... including, it would appear, the attention of the BBC.
However, Mr Wolf said he agreed to interviews "in honour of Katherine" - his wife - and also because he saw a necessary relationship with a media which had helped highlight post-9/11 projects he had been part of.
..... so it's not all bad.
