Anubis C-130, how to get a trigger when troops are parachuted ?

[Frag]

Hi guys,

 

I am playing around with Anubis C-130 as seen here.  Quite a nice and fun aircraft!

I would like to create a trigger to know when the troop were parachuted. Example: I fly the C-130 over a trigger zone, parachute the troops then a "MessageToAll" would display (over the fact that the troop just were parachuted, or first troop touch the ground.)

 

Do you know oh which condition I could link?

 

Thanks for any hints.
