Hornet Flight is a Second World War-based spy thriller written by British author Ken Follett. It was published in 2002 by Macmillan in the UK and Dutton in the US.
By late June 1941, the United Kingdom alone stood against Nazi Germany on the Western Front. In the East, the Russian Army was feeling the full force of Operation Barbarossa. To show solidarity among the unlikely capitalist-communist Alliance, Winston Churchill and Bomber Command planned a massive aerial bombardment of German territories. Unfortunately and inexplicably, Bomber Command's planes were getting shot down in record numbers.
Meanwhile, 18-year-old Danish schoolboy Harald Olufsen grows increasingly dissatisfied with his country's cooperation with the German invaders. His resentment of the Wehrmacht leads him to discover the truth about a hidden military installation, a truth known to only a select few in the Nazi organization. Running from the German authorities and an old family enemy, Copenhagen police detective Peter Flemming, Harald knows that he must get to Britain. But to do so in time to save the bombers, Harald has one option: flight.
Hornet Flight is a fictionalized retelling of actual events. Follett's website states that his inspiration for the story came from Leo Marks, a former Special Operations Executive employee, who wrote a brief account in his book, Between Silk and Cyanide: A Codemaker's Story 1941-1945 about two young Danes who found a derelict de Havilland Hornet Moth biplane, repaired it, and flew it to Britain. While that event inspired the use of two teen-aged Danes as his primary characters, the story of the photographing of the German radar station and flying the film to Britain was actually that of Thomas Christian Sneum, a Flight Lieutenant in the Danish Naval Air Service, who made the flight to Britain on 21 June 1941 in a Hornet with Keld Peterson, the mechanic who helped him rebuild it. Sneum was arrested as a suspected double agent before being returned to Denmark as an agent, from which he escaped again in 1942 by crossing the ice to Sweden with a fellow naval aviator.
