Brits studied suicide pigeons
British spy chiefs secretly considered training pigeons to fly into enemy targets carrying explosives or biological weapons, it has been revealed.
British intelligence set up a "pigeon committee" at the end of World War II to ensure expertise gained in the use of the birds to carry messages was not lost.
Documents now released to the National Archives reveal that the War Office intelligence section, MI14, warned: "Pigeon research will not stand still; if we do not experiment, other powers will."
Among MI14's proposals was the training of pigeons carrying explosives to fly into enemy searchlights.
"A thousand pigeons each with a two ounce explosive capsule, landed at intervals on a specific target, might be a seriously inconvenient surprise," Mr Rayner wrote.
However the internal security service MI5 branded Rayner a "menace in pigeon affairs".
