The app is a must download for anyone who has a bunch of GPS tracks lying around (either recorded by a GPS unit or obtained elsewhere). Don't think it's just for people who fly gliders (as the developers' site might suggest)-- FlightTrack works well for GPS tracks collected by car, on foot, on commercial flights, or by any other means.

After completing your trip you'll have to spend some time figuring out what elevation data (DEMs) and maps you'll need to use, but with some time and effort (and by carefully following directions on the FlightTrack site) you should be set.

Now comes the fun part: pick the appropriate map you wish to display, open the track file, and voila-- your route appears in glorious 3D.

3D? You don't see 3D? Just grab the map with your mouse and yank-- you'll be pleasantly surprised ; )

Recently I used FlightTrack for a presentation, scrolling around a region to highlight certain areas. The audience audibly gasped when I tilted the map obliquely: not a typical presentation sight gag. Afterword another presenter came up to me and asked what I was using and whether it's available on Winders. "Gee, I'm afraid not..."
