Formation Flying

I have been working on formation flying.  

There is a cpu controlled plane which is flying circuits around the island. 

 Another cpu controlled plane is flying in formation on its right wing.  

The autopilot now has a formation flying mode.  To switch between autopilot modes press 'M ' when the autopilot is on.

When the plane is in autopilot mode the plane will line up with the lead plane's left wing and fly in formation with it.

To switch between planes press 'Alt + v'.  Pressing 'v' returns to your plane.  You cannot control the cpu controlled planes but you can look around the cockpit and view them from the outside.
