Historic England, a UK government body, has launched the Aerial Photograph Explorer tool, which makes more than 400,000 aerial photographs available to view online for the first time. It includes the first photograph taken by Aerofilms, the UK’s first commercial aerial photography company, on July 26, 1919, two months after the company was founded. It shows its original home at the London Aerodrome, Hendon. All photos: Historic England
