As a schoolkid in 1970's Lubbock, TX we got to visit Reese AFB where they did jet training on the T37 and T38. The simulator room had a set of enormous landscape dioramas, my recollection is that they were something like 20 feet by 20 feet. The simulator would "fly" a camera over the diorama. There was a cockpit on hydraulic actuators. I don't remember what the display looked like (or even if I got to see it), but I do remember those huge dioramas and thinking how funny it would be if you "crashed" into a spiderweb on the simulator :)
