John Pullen has spent most of his career in media, first as a cameraman, then as a writer, director and producer of factual programmes. His worst moment came when he accidently hit Prime Minister Margaret Thatcher hard on the head with his video camera. He has also written many books over the years, both fiction and non-fiction. The latter encompasses general and professional aviation, medicine and history. A number of his novels are fantasy adventures and are aimed at "young adults and adults who are young". He has also produced a series of books about "Secret London Histories". In addition he also organises Historic Guided Walks in London. Currently he lives near London and for relaxation flies planes and plays tennis.
