A long-standing but ultimately unsupported hypothesis suggested that the Germans believed that the British Prime Minister, Winston Churchill, was on board the flight. Churchill’s history of World War II suggested that the Germans targeted the commercial flight because the British Prime Minister’s “presence in North Africa [for the 1943 Casablanca conference] had been fully reported”, and German agents at the Lisbon airfield mistook a “thickset man smoking a cigar” boarding the plane for Churchill returning to England. The death of the fourteen civilians including Leslie Howard “was a painful shock to me”, Churchill wrote; “the brutality of the Germans was only matched by the stupidity of their agents”.
Two books focusing on the final flight, Flight 777 (Ian Colvin, 1957) and In Search of My Father: A Portrait of Leslie Howard (Ronald Howard, 1984), asserted that the target was Howard instead: that Germans deliberately shot down Howard’s DC-3 to demoralise Britain. Howard had been travelling through Spain and Portugal lecturing on film, but also meeting with local propagandists and shoring up support for the Allies. The British Film Yearbook for 1945 described Leslie Howard’s work as “one of the most valuable facets of British propaganda”
The Mystery of Flight 777, by film-maker Thomas Hamilton, explores the circumstances, theories and myths which have grown around the shooting down of Howard’s plane. The film also aims to examine in detail some of the other passengers on board.
