Do any of you other old guys remember the 200 nm Government Property Black Pen? Always enjoyed base ops at a USAF base with the Air Force guys and their wiz-wheels hectically planning their x-cntry. We'd walk up to the huge chart on the wall, pull out our 200 mile pen, put it end-to-end over the chart a few times, non-chalantly say "Yeah, we can make it" and go file our flight plan. Ah, the good ol' days.....![]()
Good Lord, Zip - remember them?!? I wouldn't dream of going into an AF base Ops shop without one, even today. I can't remember how many times I've done that same bit of flight planning in A-6s and 18s. It always worked just fine if you were less than 4.5 pens... More than that and you had to hide somewhere so the zoomies couldn't see you actually checking weather, winds aloft and other such trivialities;-)
