Telegram from WSC to the President of the United States [Franklin Roosevelt] marked "personal and secret" regarding the President's proposals for the allocation of combat aircraft: states that the sole objective must be the optimum air impact on the enemy "irrespective of whether British or United States pilots man the aircraft"; calls for a common expansion plan; asks that General Henry Arnold [Chief of United States Army Air Force] and Towers be sent at the earliest possible moment and states that Air Chief Marshal Sir Charles Portal [Chief of the British Air Staff] will return with them; states that if necessary he will come to the United States himself (with hand-written annotation in blue pencil that this phrase has been omitted in all copies circulated except to the King); expresses anxiety about General Arnold's proposals for a revision of the allocation of American aircraft to the RAF, which will mean the loss of 5000 aeroplanes, and asks the President not to take any final decision without considering how these will be replaced by American units. Annotated in red pencil: "This copy not to be circulated".
