A friend asked me, I did not know, so I am asking you. Can anyone here shed light on this question? Thanks! I was remembering in '77-'79 when I was stationed on the western West German border, near Luxembourg, our F15s would scramble to intercept East German fighter jets when they crossed the border. I was wondering why West German jets didn't do this and why our guys had to cross the whole country to get to the east side to engage the violators.
