spawn airgroups?

[David198502]

ok tried again and answered some question by myself...its possible to increase the number of the planes...
after i let the hurri spawn further away and let it start on an airfield, the came doesnt crash anymore when spawning.

but it seems that after i shot down the first hurri, another spawns as expected, but after a few seconds, another one spawns without obvious reason....
happens everytime.so if i begin with one hurri, after i shot it down, i will have suddenly two enemies.
if i increase the the number from the beginning, the same thing seems to happen....but im still not sure when the respawn does take place in that situation....do i have to shoot down the first plane of the flight to trigger a respawn, or do i have to kill all planes of the flight??
