Miniflier I understand all what you say, but just yesterday I found 3 perfects F-5 cockpit picture on the web. For years in Switzerland during open days they installed ladders so that people could climb on them and seat in Mirage, Hunter and Tiger aircrafts and take nice pictures of themselves in the cockpit. Fact is there is nothing secret about a F-5 cockpit in Switzerland as in most other countries. What's usually classified is weapon range, capabilities and doctrine. (I have seen some of them during my time) Even then I think all airforce around the world know pretty well what a F-5 armed with Sidewinders is capable of doing. So this whole secret paranoia thing is quite typical of Swiss officals I would say. It's mostly funny tough.
Congrat with the seats, hope you make them with fabric cushion like Print Scale.
