Found a very nice progam couple of days ago. Runs in parallel with sbs1 and displays the detected aircraft on a google map. Mousing over will give the usual details of the aircraft with the added bonus of the route, if known. The prog also allows lookups of flights of any particular registration in the sbs1's data base.

Unfortunately there is a delay of about 4 minutes before the map to displays the aircraft detected by sbs1, so a bit difficult to use the program for a heads up re leaping outside clutching the old bino's. However, this is taken care of by switching to live sbs1 so no big deal i guess. A nice touch is that after selecting a craft, the map will automatically scroll to keep it centered.

Another, is a continuous updated readout of locations the aircraft is passing over, allbeit 4 minutes ago as it were. A voice announcement can be chosen to give details of selected aircraft too. Super litle prog, which no doubt Andrew, the writer, will make even more versatile in future updates. (Link is on my site's air page. And here Virtual Radar Server )
