GEESE V formation
Freeware only to share
This is compiled into a flying model using the default curtis jenny cfg..but with sound and panel 
changes using Ian Thatcher and Phil Crowther cfgs that I could add sounds ect..
The center source is on one of the end birds though..as I made this sometime back and started the model
from that bird and worked from it..so you fly the birds sorta from a small angle..
