EnglishRussia is an amazing source of bizarre and entrancing images, videos and stories from Russia. Their slogan is "Because something cool happens daily on 1/6 of the Earth's surface", and I really have to agree. They regularly dig up archive photos from Russia during Soviet times, during WWII, and even before Soviet times.
In this post, there are a mixture of photos taken from the air and on the ground by Nazi German pilots in the Luftwaffe during WWII, flying over cities in Russia. There are some miscellaneous other photos mixed in too.
