Operation Crossbow

Operation Crossbow (later re-released as The Great Spy Mission) is a 1965 British espionage thriller set during the Second World War. This movie concerns an actual series of events where British undercover operatives targeted the German manufacturing facilities for experimental rocket-bombs.


In 1943, Nazi Germany is developing the V-1 flying bomb and V-2 rocket. Technical issues with the V-1 lead the Germans to create a crewed version for flight testing, but the test pilots die flying it. Eventually, aviator Hanna Reitsch successfully flies the prototype, and realises that mechanical shifting of the missile's weight and change of speed requires the trim controls to be changed.
