April, 1934
All today is Nepal.
So the first fight between the NF.6 and the Ki-5 II Kai has came in.
The two airplanes have so much survivability they cannot kill each other, yet.

(The Ki-5 Kai II and NF-6 fighting)
It ended up as a draw, the NF.6 crashed and easily survived in Nepalese territory after running out of fuel, while the Ki-5 Kai II landed at the base they were fighting over.

(Picture 1: the NF.6 crashing. Picture 2: the Ki-5 landing)
But a normal Ki-5 was damaged and crash landed in a Nepalese Island.

(The Ki-5 crashing)
It ended up, heavily modified, in the hands of the Nepalese, now known as the NA.1
