well, here it is. after some time of thinkering and testing, i can proudly present you working flak... this is the unguided version, so you will need to aim it kinda close and it cant be operated by AI.
how it works: it uses missiles with a proximityDetonationRangeMax of 1000 meters and no guiding. that means, the missiles will fly really fast and straight and when they are close to the aircraft they will explode.
you have to aim fairly close, but one of the 50 rounds should hit...
