the maps a bit small sorry .....
so whats been happening is that I'm getting aircraft plots that don't produce polar plot info nor do they track across the map ...
as you can see they are close to the wash and at first I considered it military activity
any way the two errant plots are in the alltitude lollipop graph with no corresponding map plot ....I had numerous instances of this yesterday and this afternoon ranging from low level to high and from one to four aircraft seemingly ...also displays blue red and green
any thoughts ?
