I enjoy the Track log feature of SD for iPad which saves the flight track and depicts the "breadcrumb" line on the SD map. To enable a more detailed post-flight analysis, however, I normally run the MotionX GPS app in parallel with SD during flights.

The track log depiction within the app has been improved in the next version.

Thanks for the info, Steve. It would, however, be quite trivial to produce a KML output option for SD that already includes altitude data.

I just followed to suggestion to convert a SD GPX file using GPS Visualizer, but when I load the resulting KML file into Google Earth, it appears not to contain any elevation data. It would therefore be be useful as suggested to automatically attach a KML/KMZ for the email option like MotionX offers.
