The potential control loss would be any one control surface being disabled, made inefective, or posibly jammed in a fixxed position (theory only, I have no experience with shooting at aircraft) AirSoft pellets will not break control rods or servos so it would have to be from several sructurally damaging shots. Potentially a portion of a wing could be severed causing a loss of control. The source of the loss is the structural damage caused by the impact of the plastic pellets. (Aprox .25 cal)

A similar control loss could and likely would result from a "midair" which I hear is common when flying combat but I have no practical experience. It is also possible to have a midair on your regular Saturday at the feild. The difference being the loss of control would be anticipated in the shooting senario. The pilot can throttle back or even cut the throttle. If a ceiling cap of say 25 ft is made for the event the plane will not make it far before it harmlessly lawndarts. While a PAIR of combat planes at 250ft spin out of control will likely fall in a less predictable manor. However the pilots will have more time to cut their throtles assuming neither one lost an antena wire.

To avoid damages/injuries and recklessness the event would have to be planned not just a bunch of kids from "Club No Fear!" going out with anarchy on their minds. My idea may not be perfect or complete and it would have to be expounded upon with a colaberation of safety minded indeviduals to ensure the most is done to make a safe event. Thus as a a starting point I would recomend 2 pilons be erected 25 ft apart with the shooter at least 25 ft away as per AMA rule 7. The target craft would take a perpendicular flight path on the far side of the pilons. The shooter is only aloud to fire when the target is between the pilons. Giving the shooter a 60 degree firing zone hence controling the downrange. These pelets are ineffective after aproximately 200ft I would wear safety goggles and a Speedo and let you shoot at me with one of these from 200ft. Trust me you don't want to see me in a Speedo. The pilon spred (firing window angle) could be adjusted based on feild conditions. At my feild we have 180 degrees that could safely be used due to its rural location but that would remove the challenge which is after all what makes anything fun. Remember this is a basic outline and I admit it is possible I am overlooking something so all of you that never wore a helmet riding your bycycles, like me, but won't let you kids or grandkids leave the house out of fear they might get hurt trynot to attack but expound instead. Oh and tell those kids to get off of the Playstation or X-Box and go outside and play and don't come back until you skin a knee!

Excuse my poor spelling as I do not feel like proofreading right now.
