A couple of shots from the derelict aerodrome near Crail on the Fife coast. During WWII, a torus shaped torpedo trainer was constructed for training pilots. Targets were projected onto the wall, you can see the blue painted horizon in the first photo. The pilot sat on a swiveling chair suspended from the gantry overhead. There’s more photos, with some context here. The tin roof is now full of holes and pigeons have crapped all over the place, but it’s an interesting place to poke around. A window into the past, before computer simulations and assisted targeting.
