Just read a book as I occasionally do. It is called "Servants of Evil" and is recollections of WW2 by the ordinary German Army/Airforce/Navy bods. Two things I read in it had me wondering, one German guy mentions the use of helicopters by the allies and in another section it mentions that the Germans had night vision equipment. I know the Germans experimented with a tethered type of helicopter from a U-Boat to try and spot surface ships but did anyone really have and use helicopters in World War Two? Isn't there one featured in a film like "Where Eagles Dare" or similar, a Sioux if I am not mistaken? Did anyone have night vision equipment at the same time? I must admit I picked a few faults with this book and thought it was sloppy research or maybe something was lost in translation but I am curious. It is also quite surprising to read that some ex German servicemen were still of the opinion that the war wasn't their fault? Ah but you declared war on us! they say. Sorry mate, next time you can invade Poland, France, Holland, Austria and all the other countries that I can't spell and we will sit by and let you get on with it.
