How Far Can You Fly?

Over the years there have been a few great isochrone maps created with the Google Maps API, which show how far you can travel on public transit in a certain amount of time. Flight Times is the first map I've seen that shows you how far you can fly for different periods of time.

The map is very simple to use. Just click on the map and a number of geodesic circles are displayed on the map at set time periods. The consecutive circles show how far you can travel in incremental periods of time. You can even zoom in on the map and more circles will appear on the map to show shorter increments of travel time.
