AJ-37 Viggen

This aircraft is bright example of  finest Swedish military hardware -an aircraft with a look and features like few others. (it can reverse on the ground, and can fold vertical stabilizer to operate from bunkers or fit beneath highway overpass). Apart from the bulky appearance the performance of this scandinavian warriors were on par with any fighter aircraft of that era. Equipped with State-of-art radar and special tactics, it was the only aircraft, that was able to lock-on the SR-71 Blackbird sufficiently enough to be shot down this "uninvited guest".
Without any doubts it belongs in the list of my top 5 greatest aircrafts. 
The model is made from paper, released by Polish FLY producer years ago. I scaled down to 1/50 scale, and modified (interior details, thrust reverser,new roundels, signs, stencils a.o.) to more accurately represent the specific "red 18" aircraft, served in F-10 unit, stationed at Angelholm, Sweden.
Luckily, the real aircraft can still be seen at Cuatre Vientos airport museum in Madrid, Spain. If you're nearby, go and take a gander, there's also quite nice collection of other interesting aircrafts.
