5518.British conducting highly successful reconnoissance flights over German coast from which valuable information relative to enemy ships movements ascertained. Large American flying boats towed on lighters used for this purpose and with excellent results. Inasmuch as British have only three lighters operations are handicapped. Strongly recommend such lighters as have already been constructed be shipped to Killingholme at earliest possible date to augment British operation. Every effort should be made to expedite Whitings arrival with his complete detachment as it is expected our participation in these reconnoissance flights will have highly important results. All necessary arrangements for (group missing) of material and personnel at Killingholme have been made. 01324.
