Well, I'm glad somebody said it. I figured all the Hughes acolytes would jump all over me if I did...
Kelly Johnson and Lockheed's chief pilot went flying one day with Hughes in the prototype L-049 Constellation, and Hughes was so dangerous during touch-and-goes that Johnson essentially ordered Hughes out of the left seat and told the factory pilot to take the damn airplane back to Burbank. This was a very brave thing to do, considering that Hughes was a major Lockheed customer.
Hughes was not a skilled pilot.
