	During 1913 the first night landing made in England was achieved at Upavon, by Lieutenant Cholmondeley. In May 1914, Winston Churchill, then First Lord of the Admiralty, was a passenger on a flight by a Farman MF.7 biplane while visiting Upavon. Two officers of the CFS at Upavon developed the bomb sight between 1914–1915, and this was used in a very successful manner at the Western Front. The officers' mess, a Grade II* listed building, was completed in 1915.
