Banking Typhoon showing its stripes. Underwing Black-White stripes (4 Black, 3 white) was introduced as prominent recognition marker against friend-fire accidents. During Typhoon combat debut in British/Commonwealth 1942 assault on French port Dieppe, Typhoon's shape in heat of battle was readily mistaken to be a German Focke Wulf Fw-190 fighter plane and subsequently fired upon.

One revelation during Dieppe battles was Typhoon's weak tail assembly in full power dives. This occurred when RAF Spitfires mistaken Typhoons to be German fighters and fired upon their own forces, thus forcing the latter to executed escape dive. With Typhoon weighting twice as much as Spitfires, its diving speed approached the sound barrier (circa 600 mph). Stress level was too great for some planes resulting in catastrophic tail separation. Problem was remedied with reinforced braces along tail section. Dieppe Raid - en.wikipedia.org/wiki/Dieppe_Raid
