*drumrolling*
Here's the plane bulit in Korea, by Korean technology, by the Korean Aerospace Industries(KAI):
It's the Kt-1 basic trainer, guys.
648kmph
Range: can cover 1700km without fueling
10.3 meters in length, 10.6 meters in width and 3.7 meters in height.
Since April 2003, Kt-1 has been sold in Indonesia, meaning that Korea is now selling planes. Like 20 other countries are interested in this plane, go figure: http://www.globalsecurity.org/military/world/rok/kt-1.htm
The plane was introduced in November 2000. It's quite crappy compared to planes like the Hornet that can fly Mac 7 or something, but still, how many countries actually make their own planes? Now, they are making KO-1 foward air control plane, the prototype that can fire gun and drop bomb.
