Some good stuff
I especially liked the aerial reconnaissance images because that's a subject I've been trying to research for over 25 years. Not too much has been published about it. It's interesting that those images are showing an RAF Blenhiem doing reconnaissance. When the war broke out in 1939, they tried using Blenhiems for reconnaissance. It was damned near a suicide mission. They were almost wiped out. It wasn't until Sidney Cotton got to convert a couple Spitfires that the British had any sort of survivable reconnaissance capability.
