The photos are great!
If wind tunnels had test sections this long and you could photograph the test vehicle at a far enough distance we'd see the same thing if smoke was introduced into the wake.
This illustrates the magnitude of the wake and its relationship to fuel economy,and how an internal combustion 1987 Sunraycer would achieve 300 mpg.
Hucho could use these sorts of images in his books.
Thanks mucho! I would have liked to have been there.
