Not quite sure where to put this link, I guess here will do.
This is a new website that has published hundreds of old aerial shots of the UK.
Extract from their info:
The Aerofilms Collection was acquired for the nation in 2007 when the company was facing financial difficulties. With the support of the Heritage Lottery Fund and the Foyle Foundation, English Heritage and the Royal Commissions in Scotland and Wales embarked on a programme to conserve, catalogue and digitise the collection and make it freely available online.
The number of images available to view on the website will continue to grow, and by 2014, some 95,000 images taken between 1919 and 1953 will be visible online.
