changed the platform to this (left the original text) ;
[platform.0]
; platforms are the actual surface that the planes
; land on. You can define as many platforms as you
; want by adding subsequent sections with increasing
; numbers. e.g. [platform.1], [platform.2] etc.
;
; vertices should be defined in model coordinates,
; and counter-clockwise order when viewed from above.
: REMEMBER, positive z is out the TAIL of the ship
; the shape may be concave or convex
; there may be from 3 to 20 vertices (limitation
; may go away later) and they must all be on the same
; plane.
