Tracer ammunition in aerial weapons?

[Greg B]

Obviously the 1940 BoB Spitfires and Hurricanes never had cannon just machine guns, it was introduced on later versions. They did use tracer though to help with aiming, they said that in the heat of battle once engaged with the enemy it could help them lead their fire into the path of an aircraft, a bit like firing a shotgun at a moving target ?? The German 109s though did have cannon during the BoB, they would wait until they saw their tracer hitting home and then engage their cannons causing huge damage. Hope this helps....
