Now that the IridiumNEXT satellite constellation is complete, and worldwide ABS-B reception is possible, many southern ocean and Antarctic flights, among others, have become visible in full for the first time.
Please consider offering alternative map projections for the above page, in particular a half-sphere orthographic projection where the user can orientate the map to have any location as the centre.
Flights paths of interest that cross or go near the centre will be rendered as straight lines with lengths proportional to real distances flown.
