But so far, that is the only one I can verify.
I don't believe David MacKay was ever a Scaled pilot. He works for Virgin, IIRC. And I know at least three of the other pilots that fly it have TPS backgrounds. Two of them fly for Virgin, the third I'm not sure which company employs him.
In any case, they are highly qualified.
