On the 19th, the 12-plane detachment of flew over to airfield at the coast, from where it took part in a bigger operation against German fighters, designed to divert their forces from 90 B-17s bombing Ramilly in France. In 1942 at Kirton, No. 303 Squadron renewed its traditional ties with the Americans , when the 94 Squadron USAAF spent some time as part of No. 12 Group. Rather jovial relations were established between Poles and American, which at the beginning were dominated by "trade"talks. A very good start to this friendship was visit paid the previous year by Colonel Cooper, one of the first American pilots in the old No.7 "Kosciuszko" Fighter Squadron.

Later on, the 303 received a copy of Collier's from the United States, where Capt. NewellO. Roberts recalled: "They sent us to train with the hottest combat squadron in Britain, the 303rd Polish Pursuit Group. They were flying Spitfires. Those Polish kids taught us everything they had learned in combat over Europe. Then we went along on seven combat operations over France. On none of these were we jumped by the Jerries. By the time we reached Africa, we knew how to sweep the sky of Jerries and Eyties. The Poles are the best sky fighters I saw anywhere." In 1942, No. 303 Squadron totaled 21 enemy aircraft destroyed, 9 probables, and 2 damaged. The unit lost 10 pilots: four killed in action, two in accidents and four taken prisoners. In January 1943, the 303 carried out regular squadron-in-rest duties: training, convoy patrols
