Here is a good one that not many know.
Why was the rudder and rudder fin painted black on the Thunderbirds F4 slot plane?
It was the only time in Thunderbirds history that this was done.



I will give you the answer if no one can get it.
And where did I get the answer, it was back in 1970 when they told us why it was
painted black at a Thunderbirds air show.
