CMAK : Flak VS planes

[jawsconan]

Hi,

I wonder what does happen to a plane when a flak fires at it (red line of fire and effective firing) in CMAK.
I noticed that the plane doesn't drop its bombs as it is targeted and is fired.
But can the Flak destroy it definitely ?
In a current scen, my Wilberwind fired on a big bomber a few turn ago. Since this action, the plane has not appear again.
Is it destroyed ?

Cheers.
