Action was light and Fighter Command losses were not combat related. In one incident a Spitfire of No 616 Squadron crashed and exploded near Leconfield during night flying practice. The pilot, Pilot Officer Donald Smith, a geography teacher before he joined the RAF, is believed to have baled out unhurt. He was promoted to Flying Officer on 3 September and fatally wounded in action on 27 September.

Another crash involved the first production Westland Whirlwind allocated to No 263 Squadron at Grangemouth. During a training flight it crashed near Stenhousemuir; Pilot Officer I M McDermott descended by parachute. He was slightly injured.
