This takes a few steps, but could be done. The NMEA logs for your flights are stored on the SD card, so you need to know how to read one of those to do this. Just eject the card & put it in your reader. The logs are stored in the \User\Logs folder. The filename is a date/time stamp from when the iFly was turned on, formatted [year][month][day][hour][minute]. If your software understands NMEA formatted data - you're done, just import the file. Google Earth however does not, so you must first convert it. This is a nifty website that will do just that: http://www.gpsvisualizer.com/map?outp.... After the file is converted to kml format, you can load it in Google Earth.
