Stopping of an image

[Deacon352nd]

I’ve placed a zone trigger to activate an image when the first allied planes within the zone. The image calls up an Intel photo from which bombing assignments are given to the rest of our group. But unknowingly when returning from the bombing mission, when the first plane again entered the zone on its return to base, the image was again displayed. 
My question is, how do I allow the image to be displayed when the first plane enters the zone on the way to target but not have it displayed after that for any reason?

You can deactivate the check zone, using this setup:

 

Check Zone ------->---<------ Deactivate Trigger

 

Target link the check zone to the deactivate trigger and target link the deactivate trigger to the check zone.
