English: WWII Anti-Aircraft Battery Control Bunker. This shot was taken standing just outside the control bunker of 644th Regiment's Heavy Anti-Aircraft Battery on Otley Chevin. The concrete is slowly crumbling and the main bunker is now flooded but the site is still intact enough to be easily recognisable. The base of what was probably a gun predictor - https://www.flickr.com/photos/tjblackwell/3380517180/ - can be seen off to the left.

Anthony Hodgetts includes tales of barrage balloons and artificial cows in his excellent account of the locality:

"This site also had a barrage balloon later on in the war, which was used for training paratroopers when the Airborne Division was formed. Many years later, when I was showing some pictures to friends, one of them, Andy Clements, revealed that he had done his basic parachute training at Carlton, being billeted at RAF Yeadon and jumping from the balloon basket. He told me that his platoon was assembled every evening at dusk, put into the back of a three-tonner and taken up to the Avro factory, where their task was to move the artificial cows around, to maintain the illusion that it was still a farm field - we were aware that something of the sort was going on, but it was only after the war that the activities of the camouflage experts of the film industry became known."
