Operation Thunder Child is a 1999 novel by British civil servant Nick Pope.
It draws on government work on UFOs and is a "what if" novel that reflects some of the author's concerns about the defence and national security issues raised by the UFO phenomenon.
The book is a techno-thriller that draws on real crisis-management procedures.
