Howcome tracer rounds always seem to bounce off things?
I've seen WWII gun camera footage of ground attacks and it's as if the whole place erupts in red sparks that seem to hang in the air.
One wartime documentary showed straffing runs in the Pacific and described this as 'triple A' but this can't be true - I'd imagine that the combined speed of an incoming plane and an outgoing round would make it practically invisible on film.
So, yeah, why do tracer rounds seem to float? Is it so that the gunner/pilot can get range information? And for every tracer round that floats, is it (un)safe to assume that there are three or four rounds of party mix going right through the target??
That footage is awesome, thanks for posting (even though it'll give me nightmares!

)
