Love it :)
I knew that , Jay Leno has a steam engine and he explain this statement
hey, you just taught me something, thank you!!
Full throttle, as fast as it will go, pushing the throttle control all the way to the fire wall.
Humm, the throttle control on my tractor is operated by hand and has a ball on the end of it. Aircraft or boats with two or more engines would have multiple throttle levers I would suppose also topped with balls. I'm betting that Dave002 is right.
I'm thinking it's an airplane pilot term for flight control settings. Read the explanation somewhere a while back. I think it dates back to WWII.Best guess, anyway.
bttw.... enlighten me!
No balls not being touched led to cheating you got it all wrong
