I have been making GPS data tracks of known WWII Aircraft crashes.

Here is a sample satellite image of several crashes.

 

Additionally, I have made a Google Earth tour.  If you have Google Earth on your computer, you can download the following .kmz file. 
Run the file and it will give you a tour of the crash sites.

If you have technical questions or suggestions about this process, let me know and I will attempt to help.
