Both Helos are waiting 15 seconds, u can them wait longer.
After 15 sec. they fly away, follow waypoints, land and wait again.
As long they are standing on the ground, the player can get in.
The same thing is for vehicles.
All U have to do is change the Timer in Events.
I dont know how make them wait so long till a player come and get in, i think u must make a new event, "wait for player to take off" or somthing like this
