Bomber Harris visits Canada (30/04/1947): MS of Bomber Harris speaking to camera (sound). He opines that the atom bomb will not make armies and navies obsolete but the taxpayer might. He endorses the idea of making one unified force instead of making do with the three traditional branches. Finally, he states that an international air force would not be effective in establishing lasting peace in the world only a federation of nations would. Force cannot establish peace, it can only suppress minorities, and that, only temporarily. CU of Bomber Harris repeating his last comment. Three vertical GROUND TO AIR SHOTs of squadron of Harvard trainers flying past. Sequence on Bomber Harris laying wreath at war memorial in unidentified city, inspecting airmen honour guard.
