Spying on the spies

I have been driving past these domes just off the M40 for years and never stopped to photograph them before. Heading home this afternoon after a morning of meetings in Leicester gave me the perfect opportunity to explore some back roads and find this view across the valley to RAF Croughton. The base is home to a communications unit from the USAF which "provides support to some civilian governmental bodies"!
