*** 4 Extra broadcast to mark the 25th anniversary

Five internationally acclaimed writers consider the impact of the momentous events of September 11th 2001.

Ten years on, these authors use imaginative letters to reflect on the consequences for Britain, America and the world.

The first letter is from novelist and essayist Caryl Phillips, who was born in St Kitts, grew up in Leeds and is now Professor of English at Yale University.

In his letter, Phillips imagines that his young nephew might have to answer a history exam question about how the crisis of September 11th, 2001 determined American foreign and domestic policy.

He gives an eye-witness account of the day and those following, reflecting how the events changed him, and his identity as a Resident Alien, someone who can live and work in the USA, but is not an American citizen.

Producer: Julian May.

First broadcast on BBC Radio 4 in September 2011.
