The next morning, accompanied by Group Captain Dowling and Squadron Leader Hutchinson, I called on Colonel Shephard, Head of the Photographic Branch of the Air Information Division, Lieutenant Colonel Fuller attended this meeting and the whole plan was discussed in detail. The Americans were very reluctant to accept the British plan as it would mean scrapping all the work they had done to date (the reporting and plotting of approximately 270 sorties) and accepting an entirely new method, but after proving to them the enormous waste in time and duplication which the continuation of their system would involve and explaining the great advantages of the British system of plotting and interpretation, they finally agreed to the following:(1) That the Americans cease the interpreation reports which they had been doing on each mission or sortie.
