The Secret War

The Battle of the Beams (1x1)

Ausstrahlung: Jan 05, 1977

The mysterious radio signals from Germany which could guide enemy night bombers to a pin-point target anywhere in the British Isles could have proved disastrous for the almost non-existent British defences. Professor R.V. Jones of the RAF Scientific intelligence recounts how the "Beams" were first discovered and then countered...with crucial timeliness.
