Out of the 55,000 planes manufactured by the Royal Army Corps (RAC) during the First World War, only around 20 remain in airworthy condition. Six of these belong to The Shuttleworth Collection at Old Warden, Bedfordshire, making it the most complete collection of original airworthy World War One aircraft in the world.

The Shuttleworth Collection is home to over 50 mostly original airworthy aeroplanes, many of them the only surviving airworthy examples in the world.

IBTimes UK presents a look at five of the WWI biplanes in the collection. See the Shuttleworth website or visit the aerodrome near Biggleswade to get a closer look.
