The commander of the Northolt RAF station, W/Cdr Stanley Vincent, like many of the RAF high rank officers, doubted the scores reported by the Polish pilots from the 303 squadron. He did not believe that the Poles obeyed the regulations. He wanted to see personally what was true. One day he flew together with the 303 squadron and observed the fight against the German bombers. After the combat he said: “Suddenly the sky became full of firing aircraft, parachutes and parts of broken wings". Vincent tried to fight, but every time he wanted to attack the Germans, a Polish pilot anticipated him. So he did not manage to fight in this battle. After the landing he said to the Intelligence officer: “My God, they are really doing it!".
