It's hard because ADs don't have a brief line of text that you can clip out (following HN guidelines) yet you don't want to have title that's multiple lines long. The title does indicate that it's not all planes ("Some") but fails on the bigger issue that it's a pretty limited set of airport runways. From a software perspective (I spent a lot of time writing software for CAD systems and CNC equipment), the combination of certain latitude/longitude values and 270 degrees (which is Pi in Radians) sounds like a classic divide-by-zero problem. We had a potentially less dangerous issue with a CAD system that could show the tool path of the generated CNC. The CAD system shared the path formulas with the CNC equipment and for a certain "design", the CAD system showed the tool immediately jumping to a location about two inches away. This had never been observed on the CNC equipment after years of operation. We loaded the same CNC into the milling machine without a tool or work piece and sure enough, the same instruction/coordinate combination caused the mill to jump those two inches at its maximum feed-rate. Needless to say, finding and fixing this bug became our top priority!
