Balls to the wall did not originate with steam engines, as some of these "authority" figures on the matter state.
Remember, there were no televisions back then, nor radios, the primary media was writing in books and magazines.
An extremely cursory Google search will show you this term originated with pilots OF THE VIETNAM WAR ERA.
