Village of Stars (1962)
Hitchcock bought the rights to the 1960 novel Village of Stars by David Beaty (written under the pen name Paul Stanton) after The Blind Man project was canceled. The book follows a RAF V bomber crew given an order to drop a nuclear bomb, only to have the order aborted. Unfortunately, the bomb is resisting attempts to defuse it and the plane can only stay in flight for a limited time.
