Anche io ero molto scettico ma sabato scorso è uscito il seguente post sul Discord di IndiaFoxtEcho (hanno sviluppato F-35 per MSFS e MB-339 per DCS):
"...contrary to popular belief, much of the required information on the F-35 air vehicle is publicly available (e.g. academic papers) and there are dozens of videos of cockpit simulators, showing the avionics and the pilot interface in great detail. Moreover, a lot of the official aircraft documentation is UNCLASSIFIED (although it is RESTRICTED). Long story short, the F-35 is actually better documented than most people think - and it IS better documented than the F-22, and even (to a much lesser extent) than the Eurofighter.
THere are, howerver, some critical areas in the development, such as the actual performance of the radar and the sensors (that is CLASSIFIED) and the actual radar cross section (which can be, to some extent, simulated with commercially available tools such as HF-SS or CST).
So, yes, there will be areas in which ED will have to guesstimate some things - so it will not be (OBVIOUSLY) 100% REAL. But (spoiler) NO SIMULATION IS 100% REAL."
