Download files for the still photographs are Zip files.

Download files for the videos are WMV files.

These are large files. My apologies for that, however the original size and quality has been retained for those who may wish to do some photogrammetry projects on the vehicles. I suggest you download over a period of several nights, unless you have VERY high-speed internet.
