 Jones, who was highly regarded by Churchill and eventually rose to the position of Assistant Director of Intelligence (Science), found the "Oslo Report" extremely useful in anticipating and countering the deployment of new German radar systems, and the radio beam systems used to guide German bombers to their targets.The existence of the "Oslo Report" became more widely known through a talk given by Jones in 1947, although he did not become aware of its author's identity until late 1953, finally confirming it by meeting Mayer in 1955.Jones agreed to keep Mayer's identity secret, to avoid possible retribution against Mayer and his family.
