One Major problem with your logic Major Tom, it's incorrect. Many squadrons in WWII quit using tracers to help get the drop on unsuspecting targets. Movies show tracers because they're movies. I really hope you don't count on Hollywood to recreate history for you, God help us all. But seriously, read some accounts from the pilots who were there and fought in the skies above Europe or in the Pacific. Bottom line is.....it's your job, and your teamates job, to maintain situational awareness and keep an eye out for cons on your six.
