Don, this is on the wishlist.
We can currently take the past flight logs from the iFly Devices and then drop them into gpsvisusalizer.com and see the flight path over a google earth image. That is due to having access to the SD card. We are working on this feature for Android and iOS device to have a simple export option. It's possible for Android since there is a file explorer, but it's more complicate than most care to bother with.
Our saved flight plans support GPX files. Need to know a little more if you are wanting past flight logs or past flight plans. The logs is your actual breadcrumbs trail, the flight plan is your waypoints in the plan. What the intent of use is can better determine this for us too.
