A friend emailed me this link last night. It's a slide show of comparisons of a group of shots from both D-Day and recent photographs. The thing is, the photos were carefully lined up to be the same perspective and scale for the two scenes some 70 years apart.
Click on the link and at the top you'll get a picture of a port used to stage landing craft for the invasion.
There's ten of them, full of amazing similarities and differences. Go check it out.
