Ok, I think I can seriously answer the poster's question.
So, the problem with getting a color pic of an invisible plane is obvious. But what if there was another way to view it?
So, I decided to watch "Predator" 53 times and then called up the Prop Department for United Artist Pictures who allowed me to use the Predator bodysuit.... here is the pic of the plane as seen by the invisible Predator.
Cool. Question answered!
