I fell in love with this aeroplane long before she was introduced into the DCS. And it was a big surprise to me when she became available in this simulator. I love Viggen not for her performance or capabilities. What matters to me is the way she was designed.
Everything about Viggen gives me the same feelings, as watching classic Star Wars trilogy. I'm sure you find it odd, but this is just my very personal impression.
Watching videos with Viggens taxiing on a forest road reminds me X-wings taking off from Yavin IV. Flying low-level with pole track guidance in DCS gives me an impression of Death Star trench run.
Because of her shape with all those peculiarities like double delta wing, flaps on the canard (or the "upper wing"?), bogies, thrust reverser, splinter camouflage, and because of her cockpit with all those switches surrounded by circular white-on-black labelling printed in Swedish (foreign to me, but one of the most beautiful languages IMHO), elegantly placed MWS panels, those glowing buttons, afterburner lights, radar screen, and the most stylish instrument- simplistic HUD using lines and dots to display information, to me she looks more like a starfighter contemporary to T-65/TIE-Fighter from a galaxy far, far away, rather than a cold-war-era aeroplane from Earth.
Flying Viggen in the simulator gives me a great experience and knowledge about other ways of aircraft and avionics design and flying, than those I encounter in real life flying jets and props.
