I have downloaded all of the 'Redpack' and 'Redshots' stuff. And i was just wondering, does anyone know how redshot 3 was made.  this is a screenshot of the red arrows in a Gypo section, but the wingmen are performing a stunt?  Is there any software that can do this during the flight, to create a virtual airshow where you fly?

If so please let me know, as i try to fly aerobatics over Miegs on my own.
