I dunno... 150ish maybe? P&D day.
I always thought it meant your dispatcher giving it to you so hard from behind that your balls are against the wall.Back in WW2 (and today) many aircraft throttles were a knob on a little rod that you would pull away from the instrument panel for idle, and push it forward up against the panel for full throttle.
The knob was the ball and the wall is the instrument panel. (firewall)
So to say "balls to the wall" it means to fly your plane at full throttle.
But it's evolved to simply mean operate your vehicle at full throttle.
That post you quoted was Electric Chicken's but it says it was mine. And if you click on the "duck said" in the quote box, it goes to one of mine but that's not what it says. I don't know how you managed to screw that up but I'm laughing here. 😂They say that term is used offensively sometimes, you know.
Did I not tell the both of you a while ago on this forum something to the effect that you two post similarlyThat post you quoted was Electric Chicken's but it says it was mine.
