Peter, you just gave me an idea to add just a smidge more realism and visual interest to the starting positions. How about varying them just a small amount, so that you wouldn't get that rigid, perfect line of aircraft. How about this:
TakeOff[01]= -90,-191
TakeOff[02]= -60,-190
TakeOff[03]= -30,-190.7
TakeOff[04]= 0,-190.3
TakeOff[05]= 30,-190
TakeOff[06]= 60,-190.1
TakeOff[07]= 90,-190.5
TakeOff[08]= -75,-200.3
TakeOff[09]= -45,-200.2
TakeOff[10]= -15,-200
TakeOff[11]= 15,-200.5
TakeOff[12]= 45,-200.1
TakeOff[13]= 75,-200
TakeOff[14]=-105,-201.1
TakeOff[15]= 105,-200.5
TakeOff[16]=-120,-200.1
