I think I could maybe work on that a little bit this weekend since you asked so nice.
Thanks for the compliment, glad you find the script usefull.
I think whats great about the script is all the feedback based features I put in from users like yourself who took a little time to interact and provide some support for a lot of scripting work due to my limited scripting knowledge but extreme stubborn-ness about editing ARMA.
What i will try to do is:
If the caller is within a minumum distance to the nearest Chopper , the chopper will turn its engine on and wait for the players/squad to board and then go right to LZ/reroute mode.
I also noticed that the paradrop RTB doesnt work if your group is spread out over the map.
Ive got another script I want to release as well and Im considering adding more onto it before releasing so I have to prioritize this a bit.
